It is not painful to touch but pinching it does hurt.
It does not appear to look like a blister.
I just checked and can't feel any swollen lymph nodes in the groin area.
No burning sensation or blood in urine.
Thanks Dr. Josh. Is there something that rules out syphilis? It is small, painless and if I pinch and try to pick it up it does feel like there's content inside like a pimple - not sure if that's what firm means. Only thing from what I can find is that there are no raise edges in fact the "sore" is flush with the skin around it.
