What Causes Vein Like Cord On Penis?

Hi, I just noticed a vein like cord on my penis Wednesday. It looks like it is under the skin, the skin moves freely over it. When I get hard it looks like it enlarges and I can see it goes from mid-shaft on the left side up to my circumcision. It looks like a worm under my skin. What is it? Since then I am not getting an erection.

Hi Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concern...

The hard vein on penis on erection is totally normal. Actually it is Dorsal deep vein draining the penis.
On erection there is localized increase in pressure inside penis (due to filling of corpora cavernosa with blood). So this dorsal deep vein becomes hard & more visible on erection.
Actually you might have noticed it first time now, so you are worried

Don't worry this is fine
Hoping your query is solved.
