Penile light nerve pain

[Male19]

I am having light pain on the tip on the the penis. The pain is on the nerve, just about 1 centimeter below the urethra. It is a stinging pain , occurs multiple times in a day . No pain during erection . I have been facing this problem since a week. I am 19 years old male.

I had a htdrocele surgery 3 months back but I am not sure if these are connected as the pain started just a week back.
