Thanks hassled mum. That is very useful to know.
I will ring them up tomorrow to ask what they would like me to do. I do fit the criteria they've listed on their webpage for a BB without HRM, they just require a visit to their medical centre for a test (luckily ATOS do not seem to do the medicals as far as I can see, but it will just be my luck that the doctor I saw does these tests as a sideline!!).
Just hope this time I will actually be seen properly walking for the test this time, and not just doing 5 wobbly paces on carpet holding on to furniture, told to stop as Im clearly in pain, and then write a report which takes away my HRM
