Hey There! I'm so sorry you are hurting. I do not see muscle relaxants taking orally in your list of things you have tried. Just a thought as they do help greatly with muscle spasms. I do not battle nearly what you do with pain, but, I do when needed take a 1/2 (Prescription) Flexeril 5 mg for fibromyalgia/muscle spasms/sciatica pain and it helps greatly along with a heat pack. There are a lot of muscle relaxants out there, but, this one has worked the best for me. It is an older drug., tried and true. The newer muscle relaxants either do not work or the side effects were unbearable. Just a thought for you to mention to your doctor or you may have already tried one of these. Praying for you as this has got to be miserable. Bless You.
