Experiencing major lower back pain leg weakness burning of the thighs shocks waves going up from my ankles to the back of my buttocks certain movements make it worse. I have tried multiple injections including medial Branch blocks and epidural steroid injections. Nine of them to be exact and not one of them helped. My problem diabetic neuropathy . Come to find out after having a MRI the nerves in the canal that runs down your spine and Roots out of the tail bone the last four vertebrates of mine have shifted due to laboring which worn out the cartilage in between the vertebrates so the nerves are constantly sending signals of pain. I get very little sleep . Laying down is very hard to do every movement I make sense different nerve pain different areas constantly standings the worst sitting down very minimal treatment I'm supposed to have surgery put new spaces between the last four vertebrates hopefully aligning in the canal to relieve the pressure and the pain I'm very very scared to have the surgery don't know what to do but have it. I feel like I have no choice medication pregabalin slightly helps .
