Yesterday I noticed a small lump under the skin on the shaft of my penis. It is a cord like vein. It is on the left side of the shaft, about a 1/4 inch under the head. I have not noticed any curveture or pain, however, i just noticed it. I have been doing research on the web and I am hoping it is a thrombosed vein which should clear itself up and not peyronie's. Do you know how long it takes for pain or curveture to appear if it is peyronie's?
