It is (or actually was) a dislocated shoulder, bones around it are fine.
As said, by far the most painful experience I ever had, and that includes quite some … I am still not sure if I got full anastatia before they pulled the shoulder back, or if I just passed out once I left the X-ray room.
I was on an early morning YMS downhill when a dog rushed on the road, not chasing me, maybe just his own shadow.
I saw him coming, braked off most off the speed, but still went over the handlebar when I hit him.
I landed breast forward, and felt the shoulder snapping upon impact, all very clear.
Bad thing is that I was fully conscience of my situation, but hardly could do anything because of the pain, just laying on the pavement.
A passing scooter guy called 119.
Heads-up for him, he stayed the full time till the police and later the ambulance arrived.
Trying to trace him as he deserves a cold 6pack for sure.
