I already know I have Raynaud's Disease. But the knuckles on both my hands turn bright white when I barely bend my fingers. They also look larger to me. I have a bone spur on the top of my left hand. Would the white knuckles (looks like my skin is very thin on top of my knuckles when I bend my fingers) be more indicative of osteoarthritis or reumatoid arthritis, possibly? No real pain, just stiffness. Thank you! Yea they will cause it I broke my pinkie finger and had a lot of bone spurs in it and now my finger bends but is harder and it has what looks like white because the bone attached there and made a bump and so that bump when I bend my finger turns white. |
