Can abs be damaged in abdominal lipo and is there a test/imaging etc that can determine what went wrong?

Follow-up to: I had ab lipo to harvest fat to reconstruct arms. Was thin/was not a cosmetic procedure; had to get some fat to fix arms. Before surgery could do 55 situps/min. Now cannot do 1. Abs damaged somehow? How to determine what happened? Want to fix it. New:Went back to surgeon who did work - deserted me. PCP ordered catscan but couldn't see anything. Procedure was a couple yrs ago & can't do a situp. Can't figure out what is wrong so don't know what to do. Imbalanced w/o core strength.
