The lower knuckle of my index finger presents inflammation and redness; you can also see la little protuberance around, like dots, but not in a different color. It s has to bend, and tender. It also little iche. Not sure is it maybe an insect bite, or it should I seak a doctor. It does not seem to improve on these past couple of days. It looks like a bump on the knuckle area. Wierd,& not sure if I make any sense...
