dystonia
"I have focal dystonia as well as 2 failed back surgerys on my cervical spine that left me with nerve damage at the root level. I have been having very painful & disruptive muscle cramping in both arms & feet even in my sleep. My pain management team suggested Baclofen so started me on a course of 10mg 3x daily. So far I'm experiencing sleepiness, balance issues, memory issues, and other neurological problems but no painful spasms. 

It is my hope that as with other medications the side effects should decrease over time."
