Just had hernia surgery - 6 weeks ago. but lately, i've been feeling a little soreness in my right testicle.

This is common: Hernia surgery involves putting mesh in the location where the spermatic cord goes to the testicle. The swelling and inflammation that occurs after this surgery can irritate this cord causing you to sense pain in the testicle. This should resolve by 3 months after your surgery.

Post op swelling: This may be part of normal post op recovery after hernia surgery, of course if its on the same side as the surgery. If your surgeon manipulated the cord and placed mesh some discomfort may be ok at 6 weeks. However if you have significant swelling, worsening pain or persistent bruising you should go to surgeon to be examined.

See your surgeon: His is a common complaint, and likely to resolve on its own. However, i recommend that you see your surgeon as soon as possible for a full exam. There are some problems, such as orchitis, that do require at least some medical management.
