Found this lump in my groin area. at first it was a red lump and yesterday i discovered a huge change in it. do you know what it is?

No but discuss MD: You need an evaluation and possible imaging to determine what this could be.

No I do not: But, a guess would be it may be an abscess or a boil/carbuncle, or maybe an infected hair follicle (folliculitis). Any lesion like conditions should really be assessed with a clinical exam to get the definitive diagnosis to assure the correct treatment occurs, best wishes to you.
