For the past two days, I have had a sharp pain in my right mons pubis area. It subsides in intensity at times, but is pretty much constant. Yesterday I noticed a small lesion, no head, not raised, and barely noticeable. There may have been a hair shaft in the middle but I am not entirely sure. I have had one sexual partner for the past 5 years, but have not been tested in a while. I am terrified that this is an STD and would appreciate any feedback. Thank you.
