Hi there. I have a plate put in to my right ulna from a previous injury. I have had one plate snap on me and had to have it replaced last January. It was a hard heal, as there was a 3mm gap between both sides of the ulna, so they decided to put synthetic bone graft around it. Tonight, i accidentally had a door hit my arm in the area of the break and plate. It is now a few hours later and am in some pain. When I feel around the plate and trace the edge, where the door hit my arm, it feels "squishy" and there's a bit of a bump if I feel around the plate/bone. Unsure if it's just bruised or if I should get it looked at.
