5 weeks post op tummy tuck and muscle repair. The pain and swelling is getting worse not better. Why?

Five weeks after an abdominoplasty you want to go many changes. Increased swelling waxing and waning pain are normal. Your result will not show itself until 3 to 6 months. Your recovery will take at least six weeks to eight weeks before you have resolution of the majority of your symptoms. 

Five weeks after a tummy tuck is fairly early,however if you are experiencing more swelling, you should see your plastic surgeon to be examined to be sure you don't have a fluid collection (seroma).Best wishes,Dr.Bruno

The recovery does not follow a straight line graph of less pain, less swelling.  There are invariably ups and downs along with a steady downward course.Increased swelling at 5 weeks suggests the possibility of a fluid collection--blood (hematoma) or fluid (seroma).  Only your own surgeon can offer reassurance on that, so a call is appropriate.Thanks, all the best
