I'm a bit perplexed here myself Yabbit.

Diclofenac, or Voltaren as it's commonly known as, is an anti inflammatory used in the treatment of arthritis. If I remember correctly, Voltaren was taken off the market here a while back because of it's nasty side effects (like heart attacks).

I can't understand you being ordered this medication for spasms, and knowing what I do about the drug, I'm at a loss to understand how it could possibly help in any way for the condition your doctor has ordered them.

In MHO, you'd have better luck using Magnesium than Voltaren.
