Post hysterectomy hot foot. What to I do?

Ever since I was a child, I have had cold feet. I used to take a hot water bottle to bed every night to warm my tootsies. I had a total hysterectomy at 38 and from that day forward ( I am 43 now), I have had a problem with HOT feet. Yes I am on estradial and still experience hot flashes and night sweats and nights when sleep is only in my dreams. But the hot feet drive me crazier than the rest. Now I take a COLD water bottle to bed, but with miminal results. This is worse than the night sweats. At least they come and go. This just stays. Help.
