Lymph nodes are tiny capsules, about the size of a pea or small bean that are filled with the cells that help protect the body from illness, which are types of white blood cells called macrophages and lymphocytes. When you get ill, these cells go into action to fight disease, and the lymph nodes may swell due to presence of disease or abnormal tissue in the lymph nodes. There are actually several reasons why lymph nodes become swollen, and many conditions that can cause painful swollen nodes. Which lymph nodes become swollen can sometimes help track which diseases are creating the problem.

Lymph nodes become swollen usually from bacterial or viral infections. As bacteria or viruses invade the nodes, they harden and inflame, and they can really begin to hurt. With colds and flus, you may note painfully swollen nodes around the throat, under the arms and at the groin. When lymph nodes reach very large sizes, especially those around the throat and under the jaw, you may have mumps. Other conditions may sometimes cause large lymph nodes around this area, like strep throat, measles, ear infections, cat scratch fever, gonorrhea, syphilis, toxoplasmosis, or mononucleosis.

Sometimes lymph nodes become swollen and indicate an infection present elsewhere in the body. For instance, if you have an infected cut or wound, or you have a blood infection, you may note lymph nodes become swollen throughout the body. Usually they are most swollen closest to the infection, if it’s on the skin.

In some cases, autoimmune disorders mean lymph nodes become swollen more or less chronically. This is because the body turns on itself, and produces extra white blood cells to attack regular aspects of the body it views as foreign tissue. Typical autoimmune disorders like lupus, rheumatoid arthritis, Hashimoto’s thyroiditis, or HIV may mean lymph nodes become swollen or remain swollen for long periods of time.

Swollen lymph nodes can also indicate the presence of foreign abnormal tissue in the nodes, in other words forms of cancer. Lymphoma for instance, specifically attacks the lymph system, and may result in one or more lymph nodes swelling. In other cases, blood cancers like leukemia, mean lymph nodes become swollen.

A swollen lymph node is usually considered to be .39 inches (about a centimeter) in diameter. You’ll definitely be able to feel swelling in most cases, and it can be painful. When you’ve had a doctor identify the cause, treatment of the causal factor can help gradually bring down lymph node swelling. In the interim, while treatment has not yet worked, you can address the discomfort by taking anti-inflammatory medications like ibuprofen. You can also use warm compresses on the swollen nodes to help bring some relief for the condition. Given the potentially serious causes of swollen lymph nodes, do check with a doctor if lymph node swelling doesn’t reduce in a few days.

I am a 24 year old female and when i went to sleep last night everything was okay. When I woke up this morning, the left side around my jawline became really badly swollen on only my jawline on the left side.

Does anybody know what this might be and what might be making this happen to me? If anybody has any information about this, please let me know about it. I am getting very scared about what is happening to me right now. Please help me. Any kind of good news would be greatly welcomed.

I'm 17. Ive been known to suffer from hypochondria, but my neck hurts so bad. The back of my throat on the inside is like green and yellowish, and I have a lump on my neck that is not noticeable unless you actually touch it.

I get random pains in my neck and sometimes the back of my neck. It scares me because I can never tell if its my hypochondria or not. Also sometimes it's hard to swallow my food and the pains keep me from sleeping. Anyone know if I should be worried?

Syphilis has a lot of the symptoms you guys have stated. I am currently waiting for my blood results. I believe I may have caught it ten years ago from an older woman. I am only 26 now and have been ill for two months.

I'm convinced I've got syphilis and it is clear to me now this woman knew she had it as she got a check-up soon after and told me not to worry because she was all clear. The unprotected sex was accidental and she kept it from me. I feel cheated that my life will end very soon.

I first noticed this lump about a centimeter long on the right side of my neck a couple years ago and I'm only 15. I went to my doctor and he said that as long as it doesn't get bigger, then I'm okay. I've had this lump for about two years or so. However, I'm sick right now and I noticed that the lump as started to hurt. Is this normal?

I have been getting these swollen glands ever since I started to wrestle again. I don't have any sort of diseases or anything and I am a perfectly healthy 17 year old. I would really like to know the reason why I keep getting these swollen glands other than serious/ slight infections. Could it be from not drinking enough water, holding my breath when lifting something heavy, or even stress?

On an x-ray several years ago, the doctor said I had a nodule in my left lung, but it was nothing to worry about. Every year they took an x-ray and it was still there.

I lost my insurance and had to go on medically indigent care (they are in no hurry). However, she decided that a ct scan was needed. The results were three very large lymph nodes around my trachea, ranging in size from about 10mm to 13mm. I have no clue what size that is. She has put in for me to see a specialist of some kind to consider a biopsy. The problem is I have severe copd with emphysema, and am high risk, but that was three weeks ago, and I haven't heard anything. I am getting concerned. I need help.

I had experienced lymph nodes swelling (lots of them) two years ago and had one sent for biopsy and was normal, nothing to be alarmed of cancer but the Doctor prescribed me medicines for TB because he told me that i have developed TB of the veins.

I finished the meds after six months but then early this year, the swelling came back again in the same area in the left side of my neck. Does it mean my TB is back? I'm going home for my vacation and will definitely consult my Doctor about this. Thanks and God bless!

I just want to know what's happening. I had a swelling in the sides of the neck. After a few days, i started getting wounds all over my scalp in the head and a disgusting fluid began pouring out. It smelled awful and was as sticky as an adhesive that I could not touch my hair and had to shave my head totally.

I was then treated for the infection and the swelling in the neck is reduced and the liquid oozing out has reduced. What is actually happening?

I have a swollen lymph node to the left of my neck close to the collar bone. I have undergone a surgery and now that lump is gone for biopsy. There was also a pus formation that they extracted. The reports will be out next week. What is the reason for this?

Why does a lymph node swell and my lymph node was not hurting at all -- only that it was jerking out of my neck which looked weird. Please advise. Regards, Leanne, female, age 26.

Swollen nodes in the neck and sore throat with white puss is classic for mono. My 12 year old son is getting over this now. Dr said it was far more contagious and easy to pick up than people think.

His started with what seemed to be a cold and fever. Mainly runny nose and finally the bad sore throat and swelling after a few weeks of the fever starting. There's a blood test for it, but not a lot of anything they use to treat it with but lots of rest, ibuprofen or Tylenol for pain and fever and lots of fluids.

Has to run its course. Ssometimes they give prednisone with it because the swelling can be so bad, also your spleen can swell so you have to be careful about exercise and sports, or any heavy lifting for a few months.

I have had a lymph node for almost ten years now on the right side of my right jaw the size of a pea. It only feels painful/sore when it inflames and my body is due to fight an infection. Is this normal for this lymph node to always be there? I am very worried about this and am making myself very ill over it.I lost my mum due to mouth cancer when I was 20 which makes me more paranoid. please help, someone.

my son had the bad kind of meningitis (bacteria) and almost died two years ago. he has been checked out and had follow ups during the last two years. In the last two months he told us that he had a knot in the groin area. He had it checked out and the doctor asked him if he been bitten or scratched by a cat. he said he had and now he said he has another knot on the other leg. he has an appointment with a doctor on the 11th of this month.

He has told all doctors that he has visited that he had meningitis. He has, as far as i know, no other problems arising from the meningitis. He is scared to death that he has cancer. He is 27 years old. He has no other knots anywhere else. What do you think can be his problem. thanks for any information.

@anon70381: This seriously sounds like an infection. If you could find a doctor who would call in an antibiotic for you it would more than likely help. Oh, I found the comment about having a lot of bacteria in your mouth sort of funny because that is really all that lives in your mouth anyway. We have staph living all over our bodies and strep all inside our mouths. Great thing we have an immune system.

Get some antibiotics because it really sounds like a bad progressive infection. About the dental issues: Peridex really helps in killing bacteria that causes gingivitis and other oral problems. Try to get some of this from a free clinic or something similar if possible. Hope this helps.

I'm 16 and yesterday i found that i could feel two bumps on either side of my neck. After reading up on what it could be, i think it's swollen lymph nodes. I have not gone to a doctor, because i live at a boarding school, so it wouldn't be easy to get there.

Today, i can feel a few more lymph nodes that are smaller but seem to be swelling as well. I'm a health freak about this kind of thing. Can someone please help me? I always get very worried and expect that i have the worst condition possible, mainly because my mother died of cancer two years ago. Does this mean it could be cancer? Please, help.

Six days ago i felt like i had a kink in my neck, and two days later i starting getting a lump. Now it's been six days and it's the size of a golf ball, and I'm in so much pain and getting very bad head aches and a fever. i went to the walk-in clinic, and the doctor told me it's an infected lymph node. He prescribed me cephalexin 500mg. It's day one of taking it and the pain is still here but he said it would take about three days for any signs of healing.

You should go to your doctor because mine's getting worse day by day.

Lymph swelling is most common for head infections, like sinus or gum disease, things that are treatable and non-life-threatening.

However, if your lymph nodes begin to swell unexpectedly and for no good reason, you begin to have a spiking fever, you need to get to your doctor right away.

You should never try to self-diagnose yourself using the internet; you're just going to run into awful stuff like 'cancer' and 'tumor' and you're going to worry your benign condition into something worse.

Drink lots of green sencha tea no matter what ails you and rest easy, get some sunshine once a day as well and after a week, 90 percent of the time you'll be feeling like your old self again.

Peace and well-being to all.

I have had a swollen lymph node in the hollow space above my left clavicle for four months now. My CBC shows a high WBC but everything else is ok. I've had an ultrasound and they can't find anything. I'm very worried. It feels better with an anti-inflammatory but it's still there. It also seems to semi go away when I take Bactrim but comes back. Could this be just a bad infection or cancer?

Looking for answers. My doctor cannot figure this out.

My son has a swollen lymph node behind his right ear that has been there for six weeks. He saw his ENT a week after I noticed it and he said it is very common.

At the time he didn't have any type of infection but a few days later he developed a rash from a viral infection. Since then the node behind his ear hasn't changed at all -- hasn't gotten bigger or smaller. Should I be concerned that it has lasted this long without any change?

About two days ago I woke up with a sore like on my chin and a node in my throat. I did some research and I'm pretty sure it's a lymph node but now it's hurting around my jaw line and it hasn't gone away. The node is also starting to hurt a little.

Any suggestions on what it could be? I haven't been able to go to the doctor because I don't have insurance. I'm taking ibuprofen for the pain.

If anybody could give me some answers I'd appreciate it. Also I have a runny nose and it has been that way for quite awhile now and it's starting to drive me crazy. Could that be the reason why I have a lymph node? Thank you.

Dear "anon70381" I doubt you have cancer, especially if they did blood work on you and everything. What it sounds like to me is a very nasty infection. Most likely strep throat if you have the white dots on the back of your throat with pus coming out.

Strep throat can also cause lymph nodes to become swollen especially around the site of infection. But please, try to think positively, as our thoughts do have a major affect on our bodies. If you truly believe you're sick then you will be! You should read "You Can Heal Your Life" by Louise Hay.

I'm 22. And a few days ago I woke up with my neck being very sore, like I got hit. Two days later it turned into a lump, and a big one at that. The largest part is just under my chin, but it follows my jaw line and then down my neck.

I went to the doctor and he said I had and infection in my lymph node, but it is abnormally hard. I'm currently on penicillin. I hope it works.

i am mike, a 32 year old smoker trying to stop! Three or four months ago i got a severe scratchy throat, then a very, very sore, on fire throat. My right tonsil started to swell and got inflamed then had flu like symptoms.

I went to doc and got antibiotics and it cleared up in a week. But a week later it came back in my left tonsil and inflamed it and now it goes up and down. Except i had no flu symptoms this time.

I notice now lately my neck has what i think are swollen nodes and some small nodes have gotten pretty hard to the touch on both sides. I'm not sure if that is just normal for me or not.

I had something affect the left side of my jaw where it was really sore, just below the ear and right at the ear and now cleared up.

I am concerned about cancer although the doc did not see any signs of oral cancer and i had no other symptoms. Today i notice a whitish/clear color, either swelling or lump with looks like a pus ball on my right tonsil which appears to have very small hole leaking yellow fluid!

The skin, or whatever it is, around the front of my tonsils are red and yellow i have a lot of yellow in my mouth all over, mostly around the tonsils. Also i notice the very back and the very back sides of my tongue have a white coating on it, kind of thick in places. some of that i can remove with a toothbrush, but not all, as i gag way too bad!

Now i am ashamed to admit this part, very ashamed, but i have several rotten teeth that have went into the gums and maybe the bone. I kept really poor oral hygiene i know i made a mistake and i am dearly sorry and will see a dentist when i have money to do so. i am very poor!

What i am asking is, yes i know this can be cancer -- hell anything can be cancer -- but from what you read does it sound like cancer? Everyone, including doctors i have spoke to on the radio, says it sounds like a really nasty infection. One year ago or a little over, i was scanned from head to toe looking for cancer, blood work and all, and nothing found.

Yeah i worry about cancer a lot! Also around a year ago i got bad meningitis which almost killed me and i think my teeth caused that. Please keep in mind i have very severe panic disorder.

Please be careful with your reply as a doctor is not an option for me at the moment, with no cash. Just from what you read the symptoms, the way it started out and all that is going on now, does this sound more like cancer to you or very severe infection?

And please note my mouth is most likely full of bacteria! I really can't wait to hear from you. My main worry is the lymph nodes in the neck now i recall several months ago i thought they were very large too, and the doc felt them and said none of them were swelling and to stay off the internet lol.

But i can feel a difference. the smaller ones do feel a lot harder then before. And the white crap on back of my tongue what can that be bacteria? I had two hiv tests done lately which were negative!

No weight loss, no sickness, no energy loss -- just very very depressed! Please help me to calm down just a little. But i swear i will visit a doc as soon as i damn well can. lol!

I have implants (two years now) and I was just squeezing the skin under my armpit. Minutes later it started to pulsate and a twinge of pain started to make me aware of that location I had just squeezed. Is this any indication of anything? Not too happy with they way it is not going away! I will for sure go to my doctor asap, but any info on this -- anyone?

Did you know there's something like 600 lymph glands (lymph nodes) in the body -- most are in the head and neck. Those that usually swell are those in the armpits, neck, or groin, or below the chin.
