I had my appendix out just under four years ago. It was an open appendectomy followed by a serious infection where the surgeon considered a second surgery, but that was ultimately decided against. I noticed tonight some puffy swelling around part of the scar that was forced to stay open with a wic for about a week and 1/2. It s painless. I ve had some stomach pains over the past few days, but I m also expecting my period any day, so those could have just been cramps. Should I be worried about this swelling? I don t think I ve seen it before.
