I cannot take NSAIDS either so I started taking Turmeric 500mg 3x day and it has helped decrease my leg and foot numbness and pain. If the pain is localized and not shooting down your leg your ice and heat are a good start. Try laying on the floor against a love seat or couch with your lower legs resting on a seat cushion so your buttock is up against the couch bottom front and your back is flat on floor. This position will relieve your low back pain almost immediately.
