the last thing my therapist does (after all that exercise, pant, pant) is put that lovely warm moist pad on for 20 minutes. i love it and i leave feeling great. i have one at home too. fortunatly i also have a hot tub and live in it during the winter.
for me it helps. perhaps it will help you too. remember tho to get up and move around often.
Moist heat is good. I also love my menthol based topical pain relievers. The effect doesn't last long, but if I put it on just before bed, it tends to keep me comfortable long enough that I can fall asleep.
Long warm baths. Sometimes i turn the hot really hot as i can stand because that is the only time my body feels at ease. Sometimes i am in the tub for hours. I get like a shrivaled prune. Sorry about the spelling i think its brainfog.
Life is just to short to sweat the small stuff.
If it's more muscular, trigger points I use a moist heating pad, I get the biggest I can find. I spray it with Scottish Linen Spray (lavender scent), I use it to iron too. The scent is really relaxing as a bonus. Mostly this works between the shoulders and neck.
BUT........I use ice everywhere else. Epsom salts in a nice hot bath, a candle and Josh Groban singing is wonderful to me. Showers with one of those adjustable showerheads is great. I use the one that's like rain for washing my hair, as it hurts to use anything harder, but for the neck and shoulders it's as hard as the water can hit. Hot tubs are nice.......wish I could afford one.
I got a moist heading pad. It's just the normal size but it helps so much. It came with a sponge and you just run it under warm water and squeeze the access water out and put it on top of the heating pad. It gets really hot to. When I get up I feel so much better. Until the heat wears off of course.
