Sharp pain after golf swing

I am almost 4 months out after an iguinial hernia, non-lathrascopic surgery.  All was well until last week when I over swung playing golf and felt a sharp pain in the area of the surgery.  It only hurts occasionally.   Anyone else have similar problem.

I have a similar pain in the area of surgery.  Not sure what I did: I picked up my son (7 years old) 2 weeks after surgery - not clever. But it didn't hurt then, only after I'd been sitting for about 2 hours at a desk some weeks later. (I'm now about 4 weeks out from surgery.) I have a follow-up appointment with the surgeon in 3 weeks.
