muscle spasm
"I have degenerative disc disease, with anterior cervical discectomy with fusion (bone graft/metal plate and screws) of C5,C6 & C7; for 10 years. I suffer from frequent migraines, severe muscle spasms of the neck, left shoulder and left arm. I have tried every muscle relaxer on the shelf and Zanaflex has been the only one that actually gives me relief and comfort to function and sleep through the night. The only side effect that I have experienced is dry mouth. I just drink more water.  I have constant pain and work 12-14 hours per day, six days a week. Zanaflex along with my pain medicines have allowed me to make it through the day without total misery. Also, upon waking in the morning, I don't have that "hangover" feeling as with others."
