Varicocele surgery should be done when your sperm count
is low or if there is severe pain
Most probably few Veins might have been missed during previous surgery,which got enlarged again.
Please go for Colour doppler of the scrotum with the advice of your Urologist
and get correct daignosis,Grading of varicocele.
If the pain is due to varicocele only,then Surgery is the only option.
But,there are many conditions in the Scrotum which may cause severe pain.Please exclude all the possibilities.

Wish you speedy recovery
