When I had a really bad flare, I saw a nurse practitioner who incorporated naturopathic therapies into her treatment as well as modern therapies. She did what I think was called trigger point therapy and injected a few spots in my rear with lidocaine. She prescribed Valium but also sent me to the health foods store for Traumeel homeopathic pain cream and Natural Calm magnesium supplement. It really helped.
I have sciatica. I developed it during pregnancy. It gets worse when I'm overs certain weight. The reason for the nerve compression varies from person to person. I just know as I get closer to my old weight it helps.
