HI there, so sorry for your pain. I have tarlov cysts and AA too, though a milder form. Though I use all natural supplements with only a few pharmaceuticals. Have you visited The Tennant Foundation website, arachnoiditishope.com? Dr. Tennant is a retired pain medicine specialist that offers comprehensive protocols for treating AA. There are many great Facebook groups also for AA where members can offer things to try and resources. You can also email Dr. Tennant directly and he'll respond with suggestions. tennant@arachnoiditishope.com
Hope you can find some relief and understanding. Hugs.
