To Pete and Dave, sorry I didn't reply, I hadn't realised I'd got a couple of comments. Ummmmm, it would appear it's not so straight forward, The place offering the exercise has to be assesed, and trained to not offer exercise where it could be harmful?? I do feel as if I'm swimming against the tide, kinda thing!! But thanks you 2.
Oh I tried to write to BM and you have to pay!! but yeah I'd forgotten to mention, how I'd not seen a dr. For 2 years.
