As others have said, the only thing that works for my left foot dystonia is levodopa. Fortunately for me, I only need a small amount (half of one 25/100 will last me about 5 hours). I have tried Botox for my neck and shoulder stiffness. It worked so-so. Takes a week or so to become effective and then lasted about 2 to 3 months. I won't do it in the neck anymore as I developed a serious swallowing issue until the drug wore off. It was really bad for a few weeks.
