Thank you everyone. No luck with a physio appointment but I have had a quick look at the Michelle Kenway site and it looks very relevant to my situation. The replies she gives in the comments sections are also extremely detailed and useful. I think I should be able to find something helpful there which is comfortable and doesnt make things worse. Thanks for your suggestions, growstuff, yes, I've got lots of tins, so will look for some gentle upper body exercises with "weights". It's very nice to get these positive suggestions. Thanks to everyone who has taken the time to reply to my post.
