In reply to alx:
Well as far as my finger injuries are concerned, yeah that's pretty much what I've done, but I've never (yet) had a really bad finger injury - you can sometimes need surgery right? Now when it comes to elbows, shoulders and knees I've had surgery twice, should probably have had it another time (or at least been given the option) and for the shoulder didn't need it after various docs had a good look at two different MRIs.
I suppose I'm suggesting the doc route also because personally, when I've had a proper diagnosis that's always the first step to feeling better about the injury. I always find it nasty not knowing for sure what I've done.
Good to hear that about the NHS, I've heard some horror stories from friends. Not that it matters for me actually, as I've decided to give up injuries, I've had more than enough.
