Frank, sorry to hear of your back pain.I too have much pain, I have degenerative discs, doctor says there is nothing they can do. He suggested I try LIDOCAINE patches.You have to have a prescription for the 5% , but you can get 4% over the counter ( one brand is ASPERCREAM ) you can wear them for 12 hours on and 12 hours off. They help me very much. 4% costs about $8.00 for 5 at Walmart.
Good luck and hope you can get better.
Eddie
