i could have a case of lfs wrist. as it sometimes gives a cracking sound that doesnt sound good. but that could also be down to playing to much guitar.

If we're playing this game. I have:

LFS Neck
LFS Wrists
LFS Shoulder
LFS Ankle
LFS Arse (unless I use the cussion)
LFS Back
LFS Eyes
LFS Leg

All problems which get aggrevated to a state of "hoshit I have to stop" due to playing LFS.
