Please post photos as without them, we are just conjecturing. Swelling goes down in strange ways and it is possible that your upper abdomen in that area hasn't healed evenly yet as compared with other parts of the adomen. Perhaps you had liposuction or the dissection was more complex there. Continue to followup with your plastic surgeon.
Without photos it is not possible to offer an explanation. It takes weeks to months to completely heal from Tummy Tuck surgery. My recommendation is to contact your Plastic Surgeon as soon as possible for an exam to verify you are healing normal.
- It is difficult to be sure without a photo and an exam
- If you had liposuction in this area, it may be scar which will subside.
- It may be swelling around the muscle sutures, if it is on the abdomen, not the chest.
- This also is likely to subside with time. Best wishes.
