I keep wondering what's the difference between ice and heat? When I hurt, I prefer heat over an ache, so is it damaging if everyone keeps saying ice? I understand ice in the first couple of weeks, to reduce swelling, bleeding, imflamation etc, but now, is it really any better than heat? Especially when I get more relief from a heat pack. We have those seed filled bags you put in the microwave, they're long enough to wrap around 1/2 my upper thigh/hip. I did have a lot of muscle spasm problems with the impingement if my hip got stuck, and the GP recommended heat to ease the thigh spasms, not sure now if it's appropriate for post surgery though. Not immediately after, but 3-4 + weeks on. Any opinions and experiences welcome.
