I used the heating pad! Is this on and off stinging normal?

Hi,  Various feelings around the incisions are quite normal, especially in the early post op period.   However, a heating pad over tissue that has decreased sensation is totally contraindicated.  Full thickness injuries can come from this and I say this from personal experience in my practice.    We strive for the best looking abdomen that we can get with a tummy tuck and a burn from a heating pad scars the redraped tissue.  Very discouraging.  Hopefully you can get your questions answered by your doctor or a covering doctor but you can see the consensus of opinions here about NOT using a heating pad. 

I absolutely DO NOT suggest using a heating pad. Unfortunately without more information, it is difficult to advise you, but remember that you just had surgery. You probably have some decreased sensation around your incision. You can easily burn yourself using a heating pad and not even feel the burn due to this decreased sensation. I would suggest you call your plastic surgeons office again.
