Drug stores sell very good heating/cold packs now that come with their own soft encasing. You can buy dry heat packs or moist heat packs depending on what works best for you. You can put them in the freezer if want cold instead, but either type can be put in the microwave for 30 seconds to 2 minutes to heat up. I have one that is clay based which produces a dry heat & another that produces a moist heat. The heat in both of them last a very long time...I'm talking hours & can be placed wherever you need them.

Its been a bit since someone posted here, but Im new and wanted to share what I have discovered.
I have RSD in 88% of my body so I go through fits of sensitivity, one is too sore, one is numb, one is hot, one is cold. Other than clothes, my biggest issue has been bedding materials. Comforters are too heavy to lay on my limbs, blankets to light to keep parts of me warm.
My hubby surprised me with some Canopy brand sheets. They are found at Wal-mart and I dont know what all these are made of or even what the thread count its, but they are absobant (sp) like cotton but as soft as silk, but not as freaky feeling as silk. (yes I know I said freaky, but, duh, I do have sensory issues...lol) They are kinda on the high end (a.k.a. expensive) but they are deep pocket (for our specialty matress), and are so kosher with my phsyco body and texture issues...
Also, my feet are always cold to your touch but are burning to me, they also sweat like an overweight football player at super bowl, I have started putting VIVA brand paper towels into the bottom of my crocs and house shoes I use a piece of two sided tape to hold it in place and it soaks up all the sweat without drenching my shoe and resulting in the foul smell of a sweaty foot (which oddly enough its always my shoes that stink not my feet....) and the viva brand is very soft and absorbant so it doesnt bother me and it takes a day to two to "fill" the paper towel.

Hi the sheets are Egyptian Cotton! I have some, they get softer as you wash them. Wonderful sheets, enjoy them...hopefully you will have a pain free night so that you may get some sleep.
