I had similar issues. I am not a health professional but my MRI sounded a lot like yours. Epidurals worked for about 3 years. I was terrified of surgery. Finally the pain was too debilitating and I gave into surgery at Mayo in 2020. I am 100% after the surgery. My suggestion is interview as many surgeons as necessary to find the most competent and experienced surgeon you can find. Ask the physical therapists who rehab back surgeries. They know who has good outcomes. I wish you the best with this journey.
