For the last couple of nights, I have awakened in the middle of the night with pain in
my left index finger
, on the inside of the finger
, between the knuckle and the joint immediately above it. Today, for the first time, I am feeling on and off "twinges" of pain during the day. I am not feeling any pain anywhere else. I did have a severe sprain of my left thumb back in 1982 but am not feeling pain in that area. I have never had an injury to my left index finger.
