Hello. Thank you very much. It disappeared again but I am pretty sure what you say is true. It was a bit painful when was disappearing. You have been a great help and I appreciate your honest answer. Now everything is as before. There is but one thing. Every time I have ejaculation it feels like some of the semen is still in my penis and cannot go out. I went to the doctor and said you have urinary infection and he gave me Ciprofloxacin 500 to use for 10 days. I doubt what you say is true and this is not a urinary infection. What do you suppose I should do?
It looks like dermatitis and raised skin rather than a welt and if it becomes painful then the possibility of Mondor’s disease should be ruled out. It is superficial thrombophlebitis of the penis. This is an inflammatory reaction to a clot within the vein. This subsequently causes blockages and dilation of the vein. It is typically painless, but can be painful.
I hope it helps. Take care and regards.
