Hi. 1989 I had 99% complete C7 spinal inury and took 20mg 3x/day till 2006.
2006 MS and upped it to 20mg 6x/day. I still get bad spasms. I passed on the pump but docs all told me its small, in your back, and works without going to head. Botox i looked into but it lasts 3 months and many bottles required = 20% copay too much. Baclofen's $2.50/month with my ins.
Wish you luck.
