Your pain over testes may be due to a condition called Epididymitis
. The cause of epididymitis has to be diagnosed and treated accordingly. Just pain killers alone will not be sufficient.
Epididymitis may be due to Tuberculosis
, urinary tract infection
, STDs etc.
So approach your surgeon once again. He will diagnose the same with appropriate investigations and you will be cured of the condition.
Get well soon.
