Yes, but your local chapter should have its membership criteria easily accessible. While you don't have a firm dx, it is definite there's something going on with you that causes great pain. If your doctor were willing to confirm that, it might be enough. Especially if it gives you access to a salve or a tincture or something else non-ingestible that will help mitigate your pain.
Let me know how it goes, OK?
Warm hugs,
