My husband was suffering from sciatica for many months without relief. He could not sleep and was in constant pain. The only thing that helped somewhat, was walking. Finally, a doctor ordered an MRI of his back, and a cyst was found inside his spine. He had surgery to decrease the cyst as much as possible, and when he got home he said he had no pain in his legs. He continues to improve and now has no pain. He came home from the hospital the same day as the surgery.
