In your situation, it is certainly worth a shot if it will save you even the smallest amount of pain or discomfort.
I think you're right. Thoroughly miserable about the whole situation. Just attempted multi-tasking putting on moisturiser with tears rolling down face. Not very successful

Thanks for all the positive thoughts - that's been great reassurance. Until now, the physio has been working quite well but yep, I don't understand the logic of continuing to try to stabilise the joints/muscles/whatever if I am actually out of alignment as surely that would just stabilise me in a misaligned position.
