Hello, I have a bump a bit bigger than the size of a pea between my scrotum, and anus. It doesn t hurt unless it is touched, and slightly from the pressure applied when I stand and my thighs come together. I just noticed it a week ago, and if there has been any growth since then, it must be a small amount. The pain is moderate when it is touched. Do I need to go to the doctor, or should I wait and see if it goes away? Thank you!!!
