I think I've sprained my shoulder. It feels as though someone is boring into the blade and sending tremors down the arm. Crunching noises and feelings iyswim when moving it. Painful but can use hand..
Went to see the GP about something else but mentioned it, she took blood pressure which was fine.
What should I do? Currently alternating ibruprofen and paracetemol, hot water bottles etc.. anything else? How long till it sorts itself?
