Testicle pain after hernia surgery

I had a hernia surgery 15 days ago and the doctors removed the clips 9 days ago as the wound was closing. It was going ok, and i feel only slight pain at the moment, however my testicle, on the side where the hernia was, is hurting me, when i walk and it hurts only on its back side when i touch it...
Is it a normal symptom of the post surgical period or do u think it might be something more important?
