Veins have started appearing after quitting from injury
About three weeks ago I started feeling pain on the lower left side of my penis, I immediately stopped but continued sex and masturbation. About a week ago what I thought was a thrombosed vein appeared on the shaft of my penis. This has gradually gotten worse as if it is spreading along my veins and now my penis is covered in bulging veins (these are mostly painless apart from those close to the head). I am 21 so I doubt this is natural, I have been to my doctor but he has no idea what it might be.
I wasn’t sure where to post this but can someone please help me?
