I'm so sorry you're going through. I suffer with chronic pain myself so I do understand. I know you're seen several Drs but don't give up. Have you seen a Dermatologist yet? If you haven't, I recommend doing so because it seems like you have a lot of skin problems. Have you been diagnosed with genital herpes? That could be the cause of the problems you're having with your penis. We're here to help anyway we can. I really wish I could give you better advice. Do make an appointment with a Dermatologist. Even if you've already seen one and they didn't help you, see another one.
