Hi there
I suffer from RSD in my right arm and left leg.
When you place your hand on the top of my arm affected by RSD, you can feel a little fluttering. This is not visible at the moment.
I have musclw spasm's in my leg too, these are visible. My spasm's hurt like hell, you can always tell when my leg is going to go into spasm because my big too shoots up, the pain gets worse and then my toes go down into spam.
My PM doctor always watches my leg when it is in spasm. I find it embarrassing. People on the stree, in shops etc also stare at it. I think it's because it is so unusual.
Wishing you well.
Alison
