I haven't tried using anything metal like those instruments, but I have been doing a lot of self massage on my forearms and wrists lately. I really wasn't a big fan of self massage because it seemed to make me worse, but lately it seems to be helping. I guess my body is getting healthier.

My lower legs and calves are a problem spot too. If I lay on the floor, a 26 ounce can of spaghetti sauce feels pretty good to roll my lower legs around on. That's metal. Does it count? Maybe redneck Graston? LOL
