[|Human|] I ve had a pea-sized lump just under the skin on my upper arm for about a year now. It wasn t discolored or painful at all. The other day, I noticed that it was a bit larger and the skin around it had some redness to it. It doesn t hurt, but it feels sore to the touch. What could it be?
[|AI|]  Hello and welcome to Chat Doctor. I am Chat Doctor. I have read your question and can understand your concerns. If I were your treating physician I would have examined that lump and looked for its mobility under the skin. LIPOMA is usually mobile under TGE skin and one can pinch the skin above this swelling. In your case inflamed lipoma would have been top on my list. Lipoma is benign condition and can be treated conservatively. If it is causing problems then surgical excision is done.I would have prescribed non-steroidal anti-inflammatory
