Vonno - At PT they wrap legs/arms etc in big chilled wraps-it really soothed my aches and pains. Plus at PT while the ice pack is on they attach electrodes to exercise the inner muscles to help - so at home when my legs or arms are real achy I have bought a number of "flexible" ice packs (found at Walgreens) that chill and then wrap them on sore muscles when Im at home.
Very soothing...I had always used heat wraps before with no relief - but the coolness does help me.
