I get this in my neck, back, elbows, knees, ankles, chest (where my ribs meet) an my right thumb, lol. So i sound kinda ill compared to u guys, lololol.
It's weird, its jus like a lil' snap, like popping bubble wrap, kinda stress releiving in a way but not like in a gettin rid of ache or pain way, tho i also, as mentined above, jus get a feeling that i should say, extend my arm, then my elbow clicks, lol, strange.
I heard in a science lesson when i was at school that its caused by a build up of gas in the joints that goes 'POP!' when u move the joint. Only thing i wanna know is... What is the gas? Where does it come from? An where the hell does it go? =/
