I too had sciatica, worst pain I ever had. Went thru the spinal injections, chiropractor, therapies, Finally had a laminectomy, which freed up some room for L4,L5. Took about 3 months for the pain to go away. I was about 80 at the time and had a bad reaction from the operation, Spent 9 days in rehab.. I would do it again,the pain was that severe.
