Do you have an auto immune disease? I have Crohn's disease and my appendix scar and another scar never heals. My appendix scar is from 1997 and regularly splits open and bleeds. Apparently due to my Crohn's I heal verrrrry slowly.. How much longer it's going to take is unknown.. pff. I have my blood tested and my C-reactive protein levels were too high and my ESR was also high. I hope you find a solution quickly. good luck.
