I am only 39, buy my body cracks and pops like an old man. After living with FM for so long, am I getting osteoarthritis? I am so stiff. I stretch it out but it doesn't loosen me up much. I have tried umpteen billion supplements and nothing helps the cramping and stiffness. IF I get looser, it only takes a few hours in bed to stiffen me right back up. My calves and legs are always mega tight as is my lower back. Any thoughts about this? What do you say to a very unsympathetic mother in law who asks "Why do you look so tired?" I have tried to explain a billion times but it is like talking to a wall.
