Hi Flora
Sorry, I'm late to this thread! I started on a post to you two days ago and lost it all when my iPad decided to have a wobbly and crashed. Lol. Not a happy bunny...
I'm down in Gloucestershire. My CRPS started in my left knee after an arthroscopy, and has since spread to my whole left side in the two years following. I'm only taking low dose Lyrica at the moment (50 mg twice a day) and the rest is pain management stuff, which works better than the meds right now
Good luck if you do have to have any procedure. It's not fun, but handled right it doesn't have to mean spread or worsening symptoms afterwards. Just be pleasant about it and give your docs the guidance. As my mum says, if you don't ask, you don't get!
Take care and keep calm
Bram.
