Tooth removal ?

I can stand the chronic pain from nerve damage after my broken neck was misdiagnosed by my HMO as stress, although my spinal cord was kinked and folded over upon itself for 4 years until I convinced them to do an xray and titanium lamination, after which I was told if I waited 2 years the nerve pain would calm down. 2 years only made them free from malpractice suits due to the statute of limitations.
However, the TMD is literally killing me. I have had so-called "TMJ athrocentisis surgery", now discredited, to 'flush' the TMjoint, where they noted that one joint had no more disc and the other completely out of place. I have had dentists cap the ruined back teeth, which has only increased the bone and facial pain. I spent years proving that I do not have migraines, but instead venous occlusions (like microstrokes) due to massive inflammation radiating from my jaws. I cannot sleep more than an hour without clenching, which is what is killing me. After 3 vials of botox each done in 12 injections the lengths of the 2 masseters, I can still chew shoe leather, although my cheeks have sunken hilariously. The botox is only safe for temporary relief, which for me is minimal and only if I tape my mouth shut, sleep on my face, and use the u-shaped springy bite wings from the drugstore (I've wasted $15,00 on dentists and am broke). I have the usual chronic illnesses due to disturbed sleep and am either in worse-than-migraine pain with spasms radiating to my toes, or recovering my ever-fewer wits like a concussion victim. Either exhausted from atrophy or in pain causing spastic colon. The strongest prescription painkillers barely dent the pain of my swollen jawbone, facial bones and nerves, and baclofen, and MS muscle relaxants like zanaflex only make me weaken further after slight temporary relief.
I haven't given up, but I could sure use some ideas on how to hang on until better therapies are devised. I have had mere hours of relief, usually followed by worse pain attacks, from physical therapy, sacrocranial massage, accupressure, massage, yoga, meditation, etc. I wonder if the biggest mistake of my life was not to take out my teeth because I have talked to many impoverished chronic pain sufferers who finally couldn't afford to pay for anything anymore, lost their teeth, and were cured.
