thanks jo, i have seen 2 PT's and it was the 2nd one i saw who first mentioned TOS....the exercises seemed to help, but they became painful a few months into the programme.

My current dr agrees that my collar bone is a little bony and is protruding slightly, but says that this can happen as we get older - but im only 26!!. I read that it can be related to TOS as it can spread over to the chest wall and cause the collarbone to slip when the muscles that hold it up become fatigued?. Ive not heard about the hypermobilised thing you mentioned?

i've just become very fed up with it all over the last few years and dont think that im ever going to receive a TOS diagnosis and be treated correctly - the dr's here in the UK just dont seem to specialise...or even believe in TOS!
