how do you know if you have a hernia?

My hernia scar has started bleeding 12 or so weeks after the operation and it feels like the hernia has re-happened. Do they tend to be re-treated?

Delayed response — generally speaking they shouldn’t but it can happen. I had an ultrasound done in December to double check on some irritation in the area and thankfully all was okay, but it can’t hurt to do similar if it’s an option for you.

I had a hernia operation when I was 10. For a couple of months after, the scar wouldn't completely heal, leaking little bits of pus through a tiny hole. Every week or two, out would pop a small knot of black thread--I was rejecting the sutures.

I kept them in an empty One-a-Day vitamin bottle, like you do when you're 10.
