I guess, it can be a very dangerous place for being injured in the work place. I have heard alot of really awful stories.
I'm always extremely careful, if it seems too turbulant and I dont feel comfortable moving around the cabin, I always go in and see the Captain straight away. And if Im chimed into my crew seat, I sit down ASAP.
I have only had minor cuts, scrapes, and the constant bruises. Ever since I have been flying, my legs and arms have always had 3 or 4 bruises on them. The first month of flying I had a permanent bruised knee. This was from closing the warbdrobe door with my leg after hanging the pax's coats.
Oh, I do get really sore feet, especially after a few long days in a row.
