I hope you get out of the hospital soon and put this hiccup behind you.
Please think about probiotics now and once you leave. You are on a very strong antibiotic that is sure to wipe out your gut flora. Also be on the look out for symptoms of c diff.
I just got back from interventional radiology where my abdomen and wound areas had needle biopsies. It is noticeably softer on the right side of the incision so hopefully that is good news. Also hoping no serious infection is found.
