Why Does my Belly Feel Like It is Pumped with Air? It Seems Hollow? (photo)

There is typically a fair amount of swelling after a tummy tuck so it is normal to have unusually sensations and fullness. If there is a concern, notify your plastic surgeon. 

  Your surgical procedure is very recent, and you are at the very first stages of healing right now. It's a normal thing to worry when you are walking on uncharted territory, I understand that. You have swelling, and possibly fluids that still need to drain post surgery. Soon, at your surgeons discretion, your drain(s) will be removed, and you will continue on your road to recovery. You are also experiencing internal swelling which takes several weeks to resolve. After a Tummy Tuck, you need up to 6 months for all internal swelling to resolve. Keep your surgeon informed as far as your concerns, and I'm sure he or she will guide you through this process step by step.
