What Is The Remedy For Scrotum Pain After The Surgery For A Painful Varicocele?

My 20 year old son had surgery for a painful left varicocele on Jan. 1. While he was in surgery they discovered an inguinal hernia (they called an old man's hernia) that they corrected with mesh insert. Now 6-7 weeks post op, he continues to have a good deal of scrotal pain, taking an extra shirt with him everywhere he goes to sit on for support of scrotum. He had been diagnosed afterwards with epidymitis and given a course of cipro followed by a course of doxycycline. He is in school so other than walking to classes, riding the bus to get there, his activity is nil. His doctors keep saying it will get better, but there is no progressive improvement. Certainly the incisional pain is gone but scrotum continues to be very painful. Where should we look next?
