stitch pain or a side abdominal cramp, post liposuction. Is this normal?

Almost 12 days post abdominal and flank Tumescent liposuction. Started to have occasional stitching pain or side abdominal cramp to the sides of the umbilicus. Sometimes with sneezing specially while sitting. 1) Is that normal?. 2)And if normal how long it will last?. I am active .3) Am I considered now out of the woods for complications?
