Suggestions: Would visit a physiatrist and try to localize cause of your discomfort. Meds are merely palliative, and will coverup but not cure. Physical therapy may be useful, and eventually a back exercise program will help. You may benefit from back injections, acupuncture, osteopathic treatments, or even prolotherapy, but you need to uncover pain generator!
