I know it may seem ridiculous, but I also suffer from regular and crippling back pain, I use this cheap bit of plastic twice daily and it really helps - backmagicworks.com
Oh, that doesn’t sound ridiculous at all. It looks like it would provide real relief for people with spinal issues. I’m not sure it would help me though, because my problem is not in my spine, but in my pelvic joints, or as my specialist so delicately calls it, “bum pain”. Heh.
I’m sorry for your pain! Commiserations.. x
