I think it is different for everyone. I use my heat pack everyday.I made it out of uncooked rice and the size I needed to fit into the spot on my back where it hurts. I love it. It helps me but like I said everyone is different. Have you tried heat or ice, Personally I do not like ice packs. You have to try and see what works the best for you and there are days that nothing helps.
Thanks, I don't like ice either, but heat isn't working. I think I might make an appointment with a Chiroparctor to see if it works.
