Very occasionally when i do shouldery press moves or sometimes hard/poor footed mantles my shoulder goes weird.
It has happened on both shoulders a number of times but not at the same time. Basically I get a very sharp stabbing pain and my arm goes almost completely dead to the point where I really struggle to lift it. I tend to try and keep it mobile and after a couple of minutes the pain subsides and I am generally able to pull at full strength again about 5 minutes later. The pain is usually, but not exclusively, focused just below the top of my scapula where it meets my arm.
I found an article on the other channel about shoulder impingement syndrome but i don't think it is this. Any other ideas?
Thank you
