Hi there!
A hernia ‘repair’ is unlikely to be the problem unless there has been a re-herniation with strangulation. Other few possible causes are GI spasms, infections or inflammations like colitis, peritonitis, diverticulitius, uretric colic etc. It would be best to get this evaluated by a primary care physician/ internist initially. Later on depending on the cause diagnosed, specialist management may be sought, if required.
Hope this helps.
Take care!
Your hernia did they put a mesh in you? at times with a mesh it could tear.
I would think a Gastroenterologist could tell you best if it is related to your hernia or if it is possibly IBS or another gastro irritation.
When I had pain exactly there, it was an infected pocket in my intestines called diverticulitis. Simple antibiotics clear it up along with watching what flares it up like certain foods (seeds, nuts, ) as in tomatoes, bananas. It can be stagnant and flare up if we eat an abundant of nuts etc.
Good luck
It could do, have you been working out with weights?
