I haven't injured it s fair as I know but I woke on Friday morning with what I thought was a dead arm from sleeping funny but it's just got worse and worse.
If I was standing facing you with my arms down by my side, the bit that hurts is facing forwards, towards you.
I can't lift my arm over my head, take my jumper if by myself for example. It feels weak but isn't weak if that makes sense. I also can't stretch it out to the side, in front of me or across my body but backwards is fine.
Any ideas? I'm quite worried.
