Thanks. I've tried ibuprofen gel and Voltarol gel. Neither are much cop and I'm sure it's not muscular as it clicks/crunches. Possibly a trapped nerve as sometimes when I'm sitting real still, I get a fluttering/tingling/minute spasming across the skin over the top of my shoulder. Going to have to give in on Monday and phone the doc although I don't know what he will be able to do by telephone consultation.
