I was diagnosed over a year ago and getting help has been a nightmare. Recent physical therapy caused such pain I got stuck immobile in Walmart with a spasm. I told the therapist what the common treatment is and she got angry. She's the expert! Ha!

If you search YouTube you will find the common exercises of "nerve flossing" and yoga: 1/2 bridge, cat/cow and others. From what Ive read epidural, shots and surgery give temporary relief. Good luck.
