I have ddd, lumbar stenosis, arthritis of the back, and a bulging disc that is pressing against the nerve in my l5-s1. I'm thinking about surgery, as nothing else has helped. The doctor thinks I should get a blocker, but my biggest concern is that nerve damage will still continue, as an emg test has shown that there is severe damage to my right side lower back, and damage too the left side also. Advice would help please. Thank you.
