This sounds like irritation and chronic skin changes from rubbing. It does not sound like herpes or an STD. I suggest you see a skin doctor and get a proper diagnosis. If the doctor feels it might help, a herpes type 2 blood test could tell you, if negative, once and for all that you don't have herpes. It's time for you to get the information you need to stop thinking and worrying about this. (Among many other things, herpes does not affect both sides of the scrotum.)
I also have a rash of great discomfort now which I am concerned about and don't know what it is. It appeared after returning from a weeklong vacation at the beach, where I would go jogging for 40-50min, 3 times/week, as I have done in years past.
I have a burning pain on an area approx 1.5inch long x .75inch wide. This area initially appeared to me to be chaffed from running, and I assumed the black dots on the tips of the hair folical looking bumps were simply a scab. Well, after 5 days, the black dots have connected together to form a large patchy areas of smooth, black looking skin, which is very uncomfortable. The area does not weep/ooze, but is slightly swolen.
Today, I am noticing the same black dots forming on an area of my penis, and they are also slightly swolen and very tender and sore. I have tried hydrocortisone creams, and now trying Desitin ointment that my baby uses.
If someone knows this problem, please send me some information to give me a piece of mind. It is the Memorial weekend and I cannot see a doctor until Tuesday. If there is something I can so, I would like to try now.
