I have been occasionally banging my hands on things like a hard wooden table, my smartphone screen, and my metal laptop keyboard. It is usually out of silly frustration but it is usually a pretty hard hit. I have also used it recently to write with a pen and that hurt a lot. Now the side of my left hand (which is my dominant hand), below my pinky finger but above my wrist, there is pain. There feels like a burning sensation especially when I use it to do anything, it hurts to make a fist but not every time I try, and there is occasional throbbing pain on the side of my hand that happens at anytime. I have had other issues with my hands, wrists, and elbows but now I m worried that this could be a fracture or something worse. Thanks.
