Lump in armpit
Hi I have a lump under my arm pit it is sore and looks like a big spot under the skin or a cyst, or boil can you help
Your question contains most of the possible answers. It could be a cyst or a boil. Another possibility is that it could be a swollen lymph gland. I would advise against squeezing it or trying to burst it because you might make it much more sore if infection is present. If it isn't showing signs of resolving over the coming days let your doctor have a look at it. Sometimes abscesses can begin in this way and they can be quite painful.
