Hi.I am a 23 year old male, about 5' 11" and weight approx 11.5 stone. I have developed a pupuric rash on my penis and my feet about 2 weeks ago. I am otherwise healthy although I have been suffering chest pains for the last 4 months. I had a chest x-ray which was clear and the doctor prescribed me painkillers and said that it was muscular and I would have to live with it until it goes on it's own accord. I went to see my gp about the rash last week. He didn't say anything about what it may be and has referred me to see a dermatologist. Do you have any ideas what this may be?
