I know pain management courses are tough, and you do have to sit there and work out what is applicable, but the tools they give can be really really helpful.
The following parts I found particularly helpful:
how stress and other factors can massively increase how bad pain feels/how little we are able to cope with - makes it less scary and a number of times I've been able to go 'Ahhhh I'm in loads of pain!!!!... hang on - I'm real stressed about x. hmm that has made me tense..hmm.. relaxation/coping strategies... feel a lot better/more in control.
not stopping doing things all-together cos they hurt once - build up to it and try it again.
Not assuming that every hurt=dislocation/subluxation - once you've had a certain number your poor little pain sensors get a bit confused - There is a lot of HMS pain that is not chronic, but some of it is so don't 'write off' the chronic stuff entirely. see where you can use it and focus on that rather than the bits where it is nonsense.
under-doing/over doing cycles and how to avoid.
Communicating in constructive ways re your pain/disability with your family and close friends.
The PMC physio generally specialise in chronic pain, so take their advice regarding it and apply as much of what they say as possible, but don't be silly either and dislocate wildly. Also remember that you aren't really there to deal with specific injuries so don't expect them to give specific injuries much attention - I know it is a tough balance to find, but Good luck to both of you.
PMCs don't cure the pain, nor do they diminish the injury, they aim to give you the tools to cope better. Even if you only come out with a slightly better idea of pacing and how not to over do/under do and you put that into use, the course has been worth it.
(Donna, yours sounds much the same format as mine, with one day a week for months then reviews. And one of the girls used to get the giggles every relaxation session cos I used to wear black leather gloves to relaxation classes otherwise I'd forget where my hands were and my brain would panic and think they'd been turned completely round at the wrist
