Eurgh, had my dentist appointment. The good news is there is a dental problem causing the pain and it’s not CRPS. The bad news is my bridge/crowns etc aren’t fitting properly anymore and it’s exposing stuff that doesn’t want to be exposed. Which means having it all replaced (£3k gulp) and means getting it done might cause problems with CRPS. So I’m going to do some research for the dentist on CRPS and dentistry, and go from there.
