Finding a good physio is key....when I was immediately post op (and before I ran into problems again with scar tissue), I saw a great physio near Reading. She told me that people in the UK need to look for physios with a qualification called MACP as this means they have done loads of extra training.
I've tried to put the website link below but can't but essentially the www you'd expect then macpweb etc should work or a google search will find it- if you choose central region, you can see who is close to Cambridge - seem to be a few working within NHS so you might be able to find out which of them specialise in upper limb problems and a few privately. Be interested in what you find out as I"ll be moving back to Cambridge in October and will need to find one too!

hope this helps
