[|Human|] I have a small pea-sized lump on the left base of my scrotum. The lump is not in the scrotum, but right where my left thigh joins with the body. The lump is hard, does not seem to move around, and almost looks like a pimple at the surface of the skin. There is only pain, similar to that of trying to pop a pimple, when I apply pressure on the lump. What can this be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You may have enlarged lymph node due to reactive hyperplasia, tuberculosis or other infection.  Or you may have some benign cyst like sebaceous cyst or Desmond cyst. You should go for 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 doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
