Pain relieving gel.

i am 100% sure that it would not affect anything under your skin specially your precious internal organs. why i said so, it's because your skin will be burned before it affects your internal organs. with that sense alone, you area already avoiding further harm to your skin before anything gets worse under it, right? the main point is, if you directly place it on your chest or abdomen, these areas have thick layers of skin, specially the abdomen, so it can create damage first on your skin before the internal organs. but that won't happen anymore co i know you'll gonna remove those heating pads/gels when it starts to get real hot on there, right? and the appropriate application of heating pads/gels, you should wrapped it with cloth (not so much think though and not thin as well) before applying in on which ever part of your skin and NOT directly on your skin.
