@Russell Fleming, I think there are important points in this thread. Could the MEA please urgently review its statement on exercise, particularly noting that there is no evidence that exercise, not even flexible, gentle exercise, cures or improves ME/CFS?
How would a person contact them and ask them to do so? Is this UK or USA? I’m in the USA, so it would or at least might be meddling if I were to write to UK organization. On the other hand it seems that whoever wrote this has never had this disease and is short of a clue.
