I have suffered from back pain for years, spent years in physical therapy, take an exercise class twice a week for strengthening and balance and been to an orthopedic surgeon who hasn't been of any help except to write a prescription for epideral steroid injections. The shots help for two or three months, but don't completely solve the problem and then at the end of three months I have to go back for another injections. Because of the pain I'm unable to do the things I like. Does anyone know what my next step should be? I'm 77 years old.
