benign essential trem
"After taking 750mg/day for about 8 months, it felt great not to have my tremor as much. But in the last 3 months I have been getting stiffer and stiffer as the days went on. I have one frozen shoulder confirmed, but my back, neck and other joints were aching too. My GP looked up primidone in his book and said joint stiffness is a side effect. So I have no choice but to reduce my dosage. A week after reducing my tremor is much worse, so I don't know what to do now as I have exhausted all other medication. "
