Looking for advice on Blaspharospasm treatment

I have 6 Botox injections around my eyes every 6 months. They are essential because I don't have enough tears to lubricate my eyes.

I have cervical and mandibular dystonia. I'm to the point they want me to get dbs. I hear and see in support groups the botox very helpful. I'm to sensitive and would have a drop everytime then choke on food that got stuck in drop. We need a CURE. Trying to be a strong dystonia warrior. Hugs

They tried me on austedo and osmolex for my tardive dyskinesia and Dystonia, but I'm one of the third that it made suicidal. They've had me on a benzo, to keep the muscles around my lungs relaxed, so I can keep breathing and they've put me on cogentin. The cogentin helps but since I've started taking it I've started having these temporary weird burning sensations in the back of my arms and upper back. I'm waiting on a new neurologist, but I had a heart attack last summer so I'm gonna mention the burning to my cardiologist as well
