I am trying to very simply depict that the character is on his knees, stooped forward with his face resting on the floor. He is holding his left arm because it hurts for whatever reason. It's important that the reader understands this description because it is a cliffhanger 'til the next section of the novel. I guess what I'm wondering, is this a good way to describe it? I am drawing a total blank on perhaps a better word for bent over on one's knees.
