The other day I flexed my neck muscles while looking in the mirror. To my surprise, the left side of my neck totally stuck out way farther than the right side. But there was no pain.
I have had a sore neck and shoulder for a week prior to noticing this, but on the right side.
Not sure if the bulging is tendons, or muscular. Do you think something is herniated? Is this just due to less activity and getting older? I am a 39 year old female.
