Commonly, stress rash is what is known as hives or urticaria, and it might occur in greater or lesser amounts under a variety of stressful circumstances. It’s important to note that urticaria has many different causes, and its presence doesn’t always indicate stress. Instead it might suggest allergic reaction to ingested food or coming in contact with substances to which the skin is sensitive. Stress rash could be the diagnosis if a person can associate the development of hives with stress. It’s also possible for high levels of stress to cause other rashes that are disease based, like herpes on the genitals or face.
Many people want to know why stress might result in a rash, and the answers to this are not as clear-cut. Stress may affect the body’s immune system, which can have an effect on inflammatory response. The reaction may be similar to what occurs when the body responds to a substance to which it is allergic, but in this instance, stress could be considered the allergen. As stress levels rise, so can inflammation and histamine levels. Essentially, some people may be having an allergic response to stress. This causes the telltale signs of stress rash where bumps, red raised skin, and itchiness may cover the body in small to large amounts.
This idea of stress allergy is an interesting one, since some people clearly don’t have and will likely never get a stress rash. Yet all people undergo stress. Some people’s bodies may simply be better at coping with difficult or anxious times, and others find that slight nervousness can trigger an inflammatory skin response. There may be physical differences in the way people handle and process anxiety that accounts for the variation in stress rash expression.
Treating stress rash can take several directions. The first of these is to promote comfort when a person has an active rash. First line treatment is typically oral antihistamines, which help dull inflammatory response and make the rash go away. This can take a few days to be fully effective.
Prevention of stress rash is vital, too. While people can’t always prevent stress, they might be able to find new methods for coping with it, such as: learning relaxation exercises, adopting stress reduction techniques, participating in talk therapy, or finding additional methods to handle high anxiety levels. Sometimes people benefit from medication to treat conditions like depression, anxiety, posttraumatic stress disorder, or panic disorder. These could also help dull the body’s response to stress. Given the individual nature of stress response, each person will likely derive a specific plan that best works, and evidence the plan is working would be reduction of stress rashes.
It shouldn't be assumed hives is a result of stress. People should also plan to see a dermatologist if they have recurrent rashes. Sometimes allergy testing is recommended to determine its cause. Since many illnesses are manifested by skin rashes, it's also good idea to get diagnosis of the rash, instead of assuming it's hives.
@Oscar23: Shingles is not highly contagious unless you have never had chickenpox in your life. If you have not had chickenpox, and are exposed to someone with shingles, then you are at risk of developing chickenpox, not shingles.
There are three things necessary to contract shingles.
1. You need to have had chickenpox at one point in your life, as the virus sits dormant in the roots of your nerves for life. You can never get rid of it, even though you recover from the chickenpox rash.
2. Your immunity is on a low.
3. A stressful event is believed to be the trigger to the dormant chickenpox virus.
With all three factors present, the chickenpox virus "wakes up" and is known as shingles.
Hives sure can be a funny thing, and sometimes people get confused by what they really are. It is important not to mistake them for something more serious.
Actually, my sister thought that she was experiencing a stress rash and refused to go to the doctor. Now mind you, she had more than just a rash. She was in some serious pain and was feeling really incredibly bad. She attributed it all as anxiety symptoms.
It eventually became more than she could stand, and come to find out she did have a stress rash of sorts. She had shingles, which is highly contagious and can be triggered by high stress along with a virus. It is a much bigger deal than the hives, believe me.
I have never been one to crumble under pressure, but I recently began to have some very major marital issues. One day, I discovered that I was having some pretty bad itching on my stomach and arms.
I was at work, and very busy, so I couldn’t just run check it out. By the time I was able to, my thighs were itching as well. I went to the restroom to find that my body was covered in a slightly raised, very irritating rash.
I had never experienced this before, and didn’t know if it could be something like the mumps or chicken pox, so I begged sickness and went to the urgent care.
Come to find out it was just a stress related rash, but boy did it scare the mess out of me! A little over the counter hydrocortisone worked wonders!
