All of these are symptoms (or can be) symptoms of crps. I am on a muscle relaxer for these exact symptoms. They became strong enough to make my great toe move away from the other toes further than I can do by myself. If left untreated, these kinds of symptoms can become dystonia.

" motor abnormalities (weakness, tremors, spasm, dystonia with fingers fixed in flexion or equinovarus position of foot). Range of motion is often limited, sometimes leading to joint contractures. "

*edit*

I would suggest discussing it with your PM. I am on clomazepan and tizanidine for these tremors/contractures. Strong contractures have stopped, but I will still get tremors.

Best to you,
