I occasionally get lumps under my skin. They are about dime size and usually disappear completely within a day or two. I have gotten them on the back of my neck, thighs, stomach and back. I might get three or four in a week and then none for a couple of weeks.
Hi, This appears to be as a being lipomas (fat swelling) appearing just below the skin. This is basically a genetic condition where you see such multiple lipomas called Drums disease. They are better left alone unless causing problems like pain when its compression a nerve or for cosmetic reasons. Hope I have answered your query. Let me know if I can assist you further.
