I developed a rash on the small of my back, where my uniform belt and pants sit. I am a law enforcement student and our pants have a "grip line" to hold our shirts in which is rubbery. I assume it's from rubbing on it, but I can't say for certain. It is on the left side of the small of my back. A day or so later, the lymph node in my groin on the left side of my pelvic girdle swelled up to about two fingers across. I went to the doctor and she said it wasn't a hernia but it is more likely a lymph node fighting an infection.
I failed to tell her about the rash, most likely because she didn't ask. My question is, could it be the rash thats causing the swollen lymph node in my pelvis(it's about 4 inches away from the penis)? Or is it something else I should be worried about. A friend said it might be Syphillis, but I have only had sex with two girls. One is my gf and she was a virgin, and the other was almost a year ago....any help would be GREATLY appreciated.
