So sorry you are experiencing such misery...

Don't be afraid to tell your doc you need to try a different AD...

Also, my neuro tries different meds to alleviate the spastic pain. I'm on baclofen and clonazipam together. I was on zanaflex, which worked really well, but I experienced irregular heart rhythm and a low pulse, so I had to get off of it.

I hope you can be proactive with your doc and try different meds. I know for a fact that cannabis also quickly relieves spasticity.

Keep us up to date, and maybe you should also try to see a therapist that uses biofeedback. It trains your body to deal with pain. Again, we are praying for you and sending you (gentle) hugs...
