muscle spasm
"I have MS and the associated chronic pain. My trapeze and entire neck and back are constantly in spasm mode. I do not sleep more of a float above sleep. My nephrologist thought this would help my torso muscle spasms, several types of headaches and facial muscle spasms plus help me sleep. No on all of the above. No sleep. No relief. A new Headache was created by this and it is causing constipation, dizziness, facial flushing, nausea, depression and tummy pain. I took one 4 mg tablet and will not give it another chance. I am miserable enough I do not need to add to my issues with this drug."
