I use a heated blanket at night...either sleeping on top of it or with it over my feet/legs (depends on where my flare up is). I've also been known to sleep with a space heater on aimed at my legs (but don't put it too close because you don't want any blankets or anything to bump it. I have a microwaveable heating pad too...but it's usually too heavy to have on most of the time. Hot baths with epsom salts are a go to for me and if I follow up with ultrasound heat therapy that can extend the relief I get from it.
