I couldn't tolerate much warm water as a soak. I soak my feet and claves in ice water before I go to work and when I get home. I found a white plastic container that will fit both my feet and is high enough to cover about 2/3 of my claves. I pour half of our ice cube maker contents in the container, fill with water and soak. I also sit on flexible ice packs under my thighs as I soak and I have two sets that I rotate through the day at work.

I call it my 'morphine'. Its the second best relief I get. The best is medical marijuana, but I can't do that until later in the evening.

Hope this helps.
