Hello. I need to figure out what type of medical specialist I should see for my medical issue. I ve been having penis discomfort for the past few weeks that comes and goes. I have a little bump under my glans where the shaft ends and my primary care doctor said that it s caused from my pubic hair. I have soma anus irritation and a couple of sensitive/dark spots on my shaft. Recently my right groin and lower abdomen has felt some discomfort. I ve already had two STD blood/urine tests; one six weeks ago and another one this Monday and have gotten great results back to rule out an STD.
