I had a small lump close to a vein on the inside of my upper arm a few inches above my elbow with a bruise. But then the lump went away and so did the bruise. Then just about 4 days later the bruise showed back up and Ive been having pain on that arm (the right one).
Hi, dairy have gone through your question. I can understand your concern.  You may have some benign cyst like sebaceous cyst or some soft tissue tumor or skin adnexal tumor. You should go for biopsy. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
