Bumped tummy after tummy tuck--damage?
Yes, you do have a bruise, and yes there IS a possibility of a torn-through stitch. But the reality is that your surgeon used more than one stitch, and the strength of your muscular repair increases as healing goes forward. If you have a visible bulge it could be a collection of blood or fluid (hematoma or seroma), or a stitch could have torn through and allowed a hernia bulge. Though this is unlikely (especially since I suspect you would have mentioned that in your question if it was present), anything is possible.
If the pain persists, or if you develop a bulge, see your surgeon. If not, you're (probably) fine! I do hate that word "probably" but that's the truth, so at this point I will wish you well and continued good healing! Best wishes! Dr. Tholen
