Ever since getting FM, it seems the joints all over my body make that popping and cracking sound quite often. I swear when I get up to walk across a room, it's like a world record amount of popping that occurs. My pelvis even "cracks" when I sit!!! I know this is harmless, as it's just air escaping through the joints. But, I have to wonder, why so much air in so many joints so often since getting FM? Anyone else's joints singing the 'Pops'?
