I have mirrored RSD in my ankles, feet also in my face. I bought a new hybrid mattress. It is like a tempurpedic but also has support from coils. I love it! It is a cool top mattress and I don't get that burning up feeling at night like I used too. I also splurged on very soft sheets. They cost me over $300.00 but they don't irritate my feet and they also stay very cool.
I did not buy from this company but here is an explanation of the mattress.

It doesn't bounce and rock like a traditional bed it conforms to my body and makes me feel really supported. I did also splurge on tempurpedic pillows and they have helped as well.
I don't like to spend a lot of money but if it gives me any sort of relief I would rather spend it on something important like a bed.
