Still Swollen Almost 11 Weeks Post-op Tummy Tuck - What is Going On? (photo)

Thank you for your pictures.  You may still have some swelling at this point but not very much.  It seems that you have a poor result with a poorly designed incision and remaining excess fat/skin.  You should seek second opinions about a revision.

Thank you for the question.
As always, it is best to be seen in person ( by your plastic surgeon) for precise diagnosis and treatment.
Abdominal wall "swelling" after tummy tuck may be related to:
1. Swelling in the soft tissues.  This may take several months to resolve and may worsen with increased activity  or at the end of the day.   Patience  is required to allow for resolution of the swelling. The swelling occurs because of the interruption of venous and lymphatic channels that occurs during the tummy tuck operation.
2. Fluid accumulation in the space between the skin and the abdominal wall muscle.  this may consist of blood ( hematoma)  or serum (seroma).  This fluid accumulation can generally be diagnosed by physical examination ( occasionally ultrasound  may be helpful).  Treatment consists of aspiration;  several episodes of aspiration may be necessary. 
3. Separation of the abdominal wall muscle repair may lead to a swelling/bulge appearance. This may be diagnosed on physical examination  with your surgeon examining you in different bodily positions. One of the steps of a tummy tuck procedure involves reapproximation (plication)  of the rectus muscles.  These muscles have spread apart during pregnancy and/or weight gain. Bringing them together again in the midline helps to “tighten” the abdominal wall as well as to narrow the waistline.
4. Residual adipose tissue may be confused for swelling. Again this is most easily diagnosed by physical examination. Additional liposuction surgery maybe necessary to improve the results of surgery.
Generally, it takes many months for swelling to resolve after tummy tuck surgery and it may take up to one year  (or greater)  a complete skin redraping  to occur.
I hope this helps.

Based on your photos, your plastic surgeon removed excess abdominal skin and fat.  However, you could benefit from further liposuction and scar revision.  I would wait another month or two prior to your revision surgery. Although most of tissue edema (swelling) should have gone away by now, you may still have some residual swelling.
