about 2 months ago, my pubic area (not the penis or scrotum) became extremly itchy with little outbreak of zits or pimple like things in various places. there was a cluster of about 5 near my right lymph,which swelled a little, and one or two to the left side a little ways below the lymph. The Itching and bumbs lasted about 4 weeks,some going away and then reappearing in the same places. i didn't try to pop any of them, but i pulled a hair near one thingy thinking maybe the hair was infected and some puss came out. It didn't blister and wasn't painful, just itchy. now the itching is gone as well as the zits, but my right lymph is still a little larger than my left, and i still have a little bump in the place i pulled the hair out and it's a kind of redish in the area but it doesn't hurt or itch.. is this an std?
