I have been encountering a weird symptom. From the last knuckle on the ring finger of my right hand, to the tip of that finger goes numb and cold, almost severely numb and cold as in I can grab that finger with my other hand and feel it is cold, but typically at work. It has happened very occasionally, and minorly while at home, but primarily at work, in fact almost daily at work. Rarely, it includes the same region of my pinky finger on the same hand, but not very often.
