Hello. On April 3, I cut open my finger just slightly above my knuckle (left hand ring finger) with scissors. About a centimeter cut, maybe a 1/16 in or less deep. Bled a bit but was under control. Cleaned with water, wrapped with gauze and bacitracin, and a large bandaid to immobilize finger. Did that for about 3 days. Healed fairly quickly. However, the finger gets stiff and is painful. The knuckle is slightly swollen...sort of pillowy. Hurts when I press on it. A teeny bit reddish but not really. Poofy. Might it be infected?
