I had a back op for back & leg pain from bulging discs & have spinal stenosis. I know how you feel. If ya GP is giving you pain killers that aren’t touching it & refuse to give you anything else then i would go to a walk in. I take pregablin, codine & baclofen which normally works well but if it’s bad i get oramorph and diazapam. They can give you other things just many GPs don’t like giving anything stronger. Hospital will probably do an mri then & also give you some pain relief that’s actually going to work. I hope it gets better soonI did! The GP prescribed me the same amount of naproxen and omeprazole to take. Never needed it, the naproxen hasnt even worked. My right leg feels like it wants to cave in and even when I walk I have a dull stiff ache
