How To Treat Severe Abdominal Discomfort With History Of Undergoing Hernia?

Approx.(10) years I had double Hernia.Approx (3) years ago I had it repaired again. I still had a certain amount of comfort. About (3) weeks ago I started to get a lot of dis/comfort , below the incision. I had a scat scan, but it showed negative-No sign of hernia. Could it be a lot of scar tissue, causing the dis.comfort.
