This morning I was sleeping on my right side as usual. Woke up and turned over onto left side. As I did so something in my upper right arm felt like it slipped out of place - not sure how to describe it other than something was clearly trapped in the wrong place and very painful! I turned onto my back and moved my arm a bit in a panic and after a few seconds felt it slip back into place with a bit of a crunchy feeling. Afterwards it was really sore, with pain radiating all the way down to my hand. It’s been about 2 hours and my bicep area is still sore when I lift my arm.
What on earth happened, and should I be worried?! When I google I can only find links related to shoulder dislocation and I’m pretty sure it wasn’t my joint that slipped. It felt like it was halfway down my upper arm... can muscles or tendons get caught out of place?!? I often feel as though the areas around all my joints feel sort of loose when I first wake up, but this has never happened before...
