I have a herniated disc L4-5. And am scheduled for a laminectomy and diectomy next week. I have had back pain for many years. The last few years my right QL spasms and causes me to become crooked. This year was the first to have sciatica pain. It has lasted for about 9 weeks and I have tried PT, chiropractic, yoga. The last few days have been good ones which now causes me to 2nd quess my desision for surgery.
