HI! A few weeks ago I hurt my palm (hit the corner of the furniture while running). the pain was very bad, the palm was hurt pulsing for the whole day, then it was a little numb for the next day, still hurt for a few day in row. Then It was fine and I forgot about it. But yesterday I was adjusting my backpack, and after pulling one of the strings I felt pain in that palm again. Then it hurt all day.. today the pain went in my fingers. The joints are hurt, its painful to bend/move my fingers, especially one of them. What could it be and what should I do? Thank you
