The hallmark symptom of rheumatoid arthritis is morning stiffness that lasts for at least an hour. (Stiffness from osteoarthritis, for instance, usually clears up within half an hour.) Even after remaining motionless for a few moments, the body can stiffen. Movement becomes easier again after loosening up.
Although rheumatoid arthritis almost always develops in the wrists and knuckles, the knees and joints of the ball of the foot are often affected as well. Indeed, many joints may be involved, even causing the spine to become misaligned. It does not usually show up in the fingertips, where osteoarthritis is common, but joints at the base of the fingers are often painful.
