I got an acupressure pad similar to this one from Walmart from my physical therapist. I tell you, I think it was the one thing that benefited me the most when my back blew up a year ago in June. Kind of hard when you first lay on it, but it got so that I would fall asleep on the darn thing. Helps break up those trigger zones. I still lay on it for about 10 minutes when I get in bed at night.
