[|Human|] Hi there, about a month ago i noticed a little lump on my left inner thigh. It wasnt visible on the surface but i could feel a hard pea shaped lump under the skin, not painful at all though. It had been about a month and a half since then and all of a sudden the lump has gotten much much bigger (about the size of a nickel) and i can now see the lump pushing out on the surface of the skin(though still under the skin) without having to feel it to see its there. The past 3 days it has been really painful ,red and sore and i can barely touch it because it hurts so much. Is there any way to find out what this is and how to treat it?
[|AI|]  Hello and welcome to Chat Doctor, A painful sore lump on the inner thigh can be due to an infectious process or due to some other painful lesion like adnexal tumor. Infectious processes include boil and folliculitis. However, the possibility of boil or folliculitis is low. The lesion is probably due to an adnexal tumor. Some of adnexal tumors are quite painful. A clinical assessment and excision biopsy of the lesion will be required. Aspiration cytology will not be feasible since aspiration requires insertion of a needle into the lump, and it will be quite painful. Thanks and take care Chat Doctor.
