Look on shoulderdoc.co.uk (Lenord Funks site) find a highly rated localish consultant and ask your GP to refer you to them. This was advice from a Dr friend of mine and has paid dividends. My employer sent me down the private route since it was an injury at work. But, they then gulped at the surgery bill, so I requested to see the same consultant on the NHS and it seems the transition from private to NHS will be easier because of it; no need for further investigation as he wrote my MRI report and has case history etc.
What I’m saying is, do some research and request the consultant/surgeon of your choice, it’s your right to do this. I also spoke to a few local physio’s for recommendations.
Interim advice is look after it, but don’t get lazy, muscle wastage in the shoulder sets on pretty rapid. Think “pre-hab” in case an Op is on the cards.
Good luck!
