as much as i would like to address your concern my worried friend there is absolutely no way for me to blindly make any type of determination about this mysterious bump. you have seen multiple doctors but unfortunately this medical provider can't see "it" to offer an opinion. if this i on your skin see a dermatologist.
is this an std? . i had unprotected sex felt a bump inside her. few weeks later i saw a bump on my penis head and it transferred to my leg. i went to the hospital and they gave me a few std treatments for what i could have had - gonorrhea syphilis and a few others. the symptoms never went away and come and go. multiple doctors cannot figure out what it is. i've had many std tests and all negative. i used apple cider vinegar to try and kill it but it just made a scar and the bump returns when i'm horny.
