i had a varicocele as well Allexx... they found it in my physical signing up for the Army.. told me i was suppose to be healed up and back ready to go in 4-6 weeks after a "simple surgery" .... something happened tho in the surgery and i was fucked up for over a year... had like 4 additional surgeries trying to correct it and series of nerve blocker injections right into the sac.... after asking them to do it every week for a year so i could goto Iraq, they finally removed my nut... then when they removed it i woke up and the chord it attaches to recoiled up into my lower abdomen and they put me right back to sleep and cut me open again to remove that... the whole thing was like 10 years ago, was brutal pain, the worst of my life ...
the only advice i can give is goto the BESTTTT highest rated clinic/hospital you can even if you have to drive 3-4 hours... I went to a little general hospital for the initial procedure and then went out to Cleveland Clinic to try to fix wtf those other docs did...
