I had some fun and games getting my shoulder sorted out until I gave up on the NHS and went private.
The doctor did at least examine my shoulder at the start, prescribed NSAID's which didn't help. Examined it again, gave me a steroid injection (in the wrong place!!!). Third examination he gave me monster strength NSAIDS's and another steroid injection (in the wrong place also) which resulted in my passing out from him repeatedly trying to get the needle in the right place. Finally I demanded a referral to a specialist who took and x-ray and confirmed it wasn't arthritis and referred me to a physio.
When I had problems with my back a few years ago I went to the hospital in Ascot (it was a Sunday and I couldn't bend). The doctor at the hospital was lovely, examined my back and told me it was an aggravated disc that had most likely slipped and then slipped back. He also noticed the congenital defect I have and spotted that I had scoliosis, gave me pills and told me to go back to my GP in a week if it wasn't any better. I went to see my GP and without reading my notes, asking where in my back the pain was or even looking at my back diagnosed me with old age and obesity (I was at the time 25-26 and a good few stone lighter than I am now).
