Perhaps go by a physio clinic too, and see what they can do for you.

I hurt my shoulder in a minor way once, and I booked a physio session at Sothland Leisure Centre. I only had one appointment (very minor injury), but it sure helped me feel better quickly.

You would likely need more than one session, but it could really help. It does not cost all that much per appointment.
