I’m so sorry to read this as I think you were hoping for more, especially after so long. At last you have what sounds like a definitive diagnosis and they offered a plan even if it’s not going to work in practice in your situation.
I know someone who was referred to The Liverpool Pain Clinic from another health area, with all accommodation covered, and it has had great results for them so it sounds like the group they’ve offered could have included some of the same approaches, although I’m just guessing here.
I hope the GP is helpful too, and yes we never know quite how the body will react to every situation. Thinking of you both.
I hope the Occupational Therapist is helpful and you get the adaptations and aids that he needs. Please push for this if you haven’t already. I posted all the numbers for Norfolk earlier in this tread.
