29 year old male. I have a lump on my inner left thigh, perhaps 2 inches from my genitals. It is hard, smooth, and appears to be separate from the skin, lying underneath. There is no visible evidence of it being there, I can simply feel it. It doesn't cause any pain. It just concerns me, probably more so because my medical insurance expires in 5 days. Is this something that should be removed, drained, left alone, or what?
