Why does the stomach tighten up after a little movement post- tummy tuck?

.The swelling doesn't change much during the course of the day. Perceptual changes might based on what you expect of the abdominal muscles that are swollen. All of the symptoms will improve as swelling subsides. Full recovery may take several months

The cause of the abdominal muscle tightening is usually muscle spasms. This improves typically over time and with rest. I encourage you to discuss your concerns with your surgeon. He/She is most familiar with the details of your surgery and how you've been progressing through recovery.

If you are doing something in particular tat is causing you tightness or pain then it is too much for you at this point in your recovery.
