I try to do the same things; running my hands under warm water before playing. I have this thing (I guess it's like a heating pad) that I put in the microwave for about a minute and it holds heat well. I will put that on my elbow and hand sometimes too. That seems to help.
It's stinks getting old! :)
Take it easy. Hope to see you around the boards.
