I have not heard of dystonia involving the leg. Several years ago, I was diagnosed with cervical dystonia. Had spasms of the left side of neck, shoulder area. This would also bring on migraines. I did see a neurologist from Rush Medical Center in Chicago who gave me a series of Botox injections on the side and back of neck, and shoulder area. It did nothing for me.

If this continues; You certainly can't continue working in a job that requires a lot of
standing. I think it would be wise to try applying for positions that would allow you to sit. Obviously, the standing is aggravating whatever is affecting your leg.

Hope you can get some relief soon.
