You did not mention why you had a varicocoele surgery, but I hope it was not for pain in scrotum because most patients will have persistent pain even after the surgery because of increased engorgement of veins in the epididymis
which is the site for storage of sperms due to back pressure from veins that are ligated at the time of varicocele
repair. Sometimes, scrotal support helps relieve the pain, but many patients need to use analgesics like Tramadol with or without paracetamol
for better relief. If no relief, you can try a tablet like Pregabalin
which helps with neuropathic pain
Hope I have been able to help you.
