A 34-yr old white male living in rural Japan, I noticed 2-3 days ago a red bump
, looked to be coming from under the skin on 1 finger. Over time noticed more - on both hands. Today, on left hand: 4 on index (2 on outside side, 1 the inside side, 1 on outside knuckle), 1 on palm, thumb-side of center. On my right: 2 on middle (1 below upper joint, index side; other palm-side knucklemost section); 1 palm below pinky knuckle. Small; size varies, but ca. sm. letter "o".
