Heat is soothing to me. For nearly every ache, I opt for heat over ice. I have a "Bed Buddy" that I pop in the microwave and drape around any sore muscle on my body. I own a hot water bottle and a heating pad.
Heat is said to improve blood flow and can help in the wound healing process. However, you should be cautious when using heat to heal after a tummy tuck.
You are numb for a while after an abdominoplasty. This is potentially harmful when mixed with a heating pad and sleep! Unfortunately, I had to learn the hard way that I could actually burn myself with a heating pad and not realize it because I couldn't feel my skin burning.
Luckily, I got a hold of some silvadene for my burn.
If you feel you need some heat, try the lowest setting and stay alert!
Don't create an unnecessary set back with your healing.
