<s>[INST] Alright so about 5 months ago i noticed a small misquito bite-esque lump on my thigh about 3.5 inches directly above my kneecap. After a month, it had not gone away but gotten slightly larger. Still thinking it was nothing, i ignored it. About a month and a half ago, i noticed the lump looked rather bruised and significantly larger, sorta like the size of the flat end of a bic pen. I accidentally cut it shaving, and since then the lump has gotten really painful, bleeds a LOT now with little effort (otherwise known as when i rub my pants against it, it bleeds), and the skin has gotten red and thick feeling around it. Whats up with this? Any ideas? [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor lie lipoma or liposarcoma or some other mass. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health. </s>
