I always use a cold.pack for that reason.

I also use a cold pack when I feel like this. Less nauseated for sure. A cold cloth on my forehead too and sleeping a bit elevated xx feel better hun

Heating pads make me nauseous too and does a pity job on elevating the pain. Cold packs cause my uterus to cramp badly. So when I want some extra punch for my painkillers to work, I use non steroid heating gels, generally used to treat back pains. I just rub them on my belly.
