Do a very LOW warm to help you thaw out. That's what I do. You have to be careful about heating pads and stronger heat sources as you could very easily burn yourself. That and lots of light external insulation! Lite blankets, socks and such. I'd found that early on? I'd be either soo cold as to turn blue or soo hot as to be beet red! Damp wash cloths on the hot sites let a slow evaporation do a job gently. AND then? You can go from HOT to COLD in minutes without warning. So? Be forewarned?
I hope we all here can help you with all your hurt, and don't please, be shy about asking questions! We all hurt. Many in different ways? But we try to help each other as best we can. 's - j
