Harry,

I have CRPS in my foot and over time, I've found out that stretching and exercises of the foot and toe are critical to my well being and are much more effective when done in "warm" water. The warm water loosens up the joints, which are especially stiff after sleeping.

I normally take a soak in the morning to ease all my other aches and pains, so I do my AM foot exercises in the tub.

Give it a shot. Good luck.
