What should I do for extreme pain & swelling 3 1/2 mos post op & what does irregularity in the rectus muscles mean? (Photo)

3 1/2 mos post op ETT & abd is still swollen &hurts. CT scan done stated: some irregularity in the rectus muscles of my abd & some extra fluid in the lower abdomen & around the incision. It is thought this is all related to your surgery however these shouldn't be present 3 months out.There was no evidence of overt infection or abscess.My PS w/o seeing me dx a seroma. What does irregularity in the rectus muscle mean? Over incision is hard on both sides, like bone. Looks like keloids & dog ears
