How many lymphatic massages should I plan for after my tummy tuck procedure?

I do not believe that having a non medical therapist push on your freshly healing abdominoplasty flap is going to do anything except separate the flap from the underlying muscle.

I don't ask my patients or recommend that they waste money on lymphatic message.  We use topifoam pads over the abdomen and flanks when there has been liposuction. Wearing this decreases swelling and bruising tremendously. You can see a big difference in thinness and pliability of the skin, without swelling, between the areas covered with topifoam (or epifoam) and those not. Swelling gradually subsides normally whatever you do, but compression with foam really helps over the first month. It is a bit inconvenient after the first week, but many of my patients like to do it anyway because they see the benefit.

Swelling is a normal part of the wound healing process. I would not recommend pressure or any type of rubbing of your abdomen after surgery until your surgeon has confirmed that is has completely healed. Rubbing or pressure can separate the overlying skin  from the underlying muscles and fascia and cause delayed healing, pain, and possibly a fluid collection to develop.
