Why is there hard lumps and numbness in my stomach after a tummy tuck?

Tummy tuck by itself will create some numbness all over the abdomen and will recover top to bottom throughout the months. But the flap is never hard  Liposuction creates the hard lumps. Maybe massage, maybe ultrasound, maybe lymphatic massage would help, all all will depend of what your doctor recommends. Be encouraged  Dr  Cardenas 

Numbness is completely normal after a tummy tuck, and should have been explained to you pre-operatively.  it is also common to get lumpiness after liposuction.  You don't mention how long since your surgery, but lumpiness usually settles over the first few months & numbness also improves over months.  Generally there will always be some residual numbness just above your scar.  See your surgeon if you have further concerns.  Kind regards

Dear Legrendre,It is very natural to have concerns after a big operation such as the one you underwent. It is normal to have numbness between the belly button and lower part of your incision. This will typically improve over the course of one year, but it is not uncommon to have some permanent decrease in sensation in that area. It is also very normal to have lumpiness from liposuction do to swelling, inflammation, and fat cells that are damaged during the procedure. This should significantly improve over time, but it will take 3-6 months. Follow your surgeon's post-operative protocol which likely involves some type of compression as well as massage. The hardest part of surgery is having patience during the recovery phase and allowing your body time to heal. Hang in there.
