About 2 1/2 weeks ago I found a lump under the skin of the top of penis at about the center of the shaft. I went to a walk in clinic a week later and the doctor said it looked like a thrombosed vein. And that it would go away on its own in about 2 weeks. Since then it has gotten bigger and they are a few more hard lumps above it. I am worried it could be Peyronie's Disease. What do you think it sounds like? what can I do about it?
