Chirley,
Perhaps your GP doesn't know what every psychiatrist knows - all antidepressants will decrease chronic pains:

The problem with antidepressants is that we never know what patient will respond to a special drug - the same as with MDS. Have you tried antidepressants before - if so you perhaps already know which drug is the best for you.
Then most drugs start with adverse effects like anxiety and sleeping problems so you have to start with a low dose combined with Valium (as you take for spasticity) or a similar drug. After 3 weeks many patients feel better in the evenings but some patients have to try a longer time before it is time to try another drug.
Kind regards
