Hi, my thumb was injured one month ago. There was a hyperextension of the thumb away from the palm of my hand. Originally, there was muscle hemorrhage in the palm of my hand, but has since subsided. Since then, the joint of my thumb, Metacarpophalangeal (MP) Joint, has still hurt a little bit and has a little bit of inflammation. 2 days ago, I went out into the cold and my hands were exposed to 15F weather and they really hurt from the cold. Since then, the MP joint has felt odd and really stiff, and a but more swollen and itchy. What is going on? Is this serious and should I see a orthopedic surgeon? I do not want to end up with arthritis in it someday, as I will need my hands for my work (currently 29 y/o f).
