I didn't understand Tony's answer in terms of " if you are in a wheelchair I would never suggest "some" positions" etc. But I thought I would add that I am a wheelchair user although I am able to walk short distances.
I am appreciating all the answers including from the USA but thought I would add that I am from the UK, in case anyone knows anywhere in the UK that might help me. I am liking the idea of trying my MP.
Thanks to everyone who answered, they all all good answers and can't choose one so will put this to the vote. Hopefully I get something soon and good luck to the people in the same boat :)
