Hi, Yes. In March Of This Year I Developed Pain

Hi, yes. in march of this year I developed pain in my left thumb, around the bone area where the finger connects to the hand, and a double jointed feeling in my middle finger on the same hand. Its more pronounced in the morning, the onset was very acute, but hasn't gone away. The pain can linger throughout the day. I have never had arthritis, and am very active and physically fit 52 yr old.
