[QUOTE=ZackJones]take a small size gatorade bottle, fill it 2/3 full of water and freeze it. I like using gatorade bottles because the sides are not smooth and the ridges feel good when you roll your foot over them. After running roll your foot over the gatorade bottle for several minutes and see if this helps relieve the pain.QUOTE]

Good therapy tip -
I like using those cold freezer gel-packs which I hold in place with an ACE bandage should I ever have any issues. But the rolling of the bottle as you describe is a good idea.
I also have one of these log rolls (in photo, from RRS) as well as "The Stick" which I tend to use after my long weekend runs. Sometimes "heat" is good too. I also found some very cool heat packs at the Boston Marathon expo last year, called "Genie Heat Pack". By just bending a tap inside it crystalizes and gets hot (good for maybe 30 min) and you just boil them for 15 min. to return them to their orginal state.
