I am 48 hours post op from a full Tummy Tuck. I am extremely uncomfortable. Is this to be expected?

At
this point in your recovery, it is much too soon to be worried about the
outcome. It takes time for the swelling to resolve. It may be 6
months or more before the shape has reached its final look. Be patient. Watch your physical
activity. Everyone is different. 

This sounds like typical pain following a tummy tuck. If you are noticing more and more swelling and tightness the main concern would be if you are bleeding. Have the drains changed color? Is there significant swelling or just skin firmness? You should have pain and be uncomfortable after a tummy tuck which is the most painful cosmetic procedure. Call your surgeon to be safe. Cramping is likely typical discomfort after this operation. 

At just 48 hours post tummy tuck, it is quite normal to be uncomfortable.  It can take several days to several weeks before one may be comfortable, especially in moving and walking.  Give things time to settle, but if you develop a fever or a particular area of swelling, redness, or tenderness, let your surgeon know.  Best wishes, Dr Lepore.
