porcupine

Then he heard the slithering. A brushing sound, a slithering brushing sound near his feet — and he kicked out as hard as he could, kicked out and threw the hatchet at the sound, a noise coming from his throat. But the hatchet missed, sailed into the wall where it hit the rocks with a shower of sparks, and his leg was instantly torn with pain, as if a hundred needles had been driven into it. "Unnnngh!"
  Now he screamed, with the pain and fear, and skittered on his backside up into the corner of the shelter, breathing through his mouth, straining to see, to hear.
  The slithering moved again, he thought toward him at first, and terror took him, stopping his breath. He felt he could see a low dark form, a bulk in the darkness, a shadow that lived, but now it moved away, slithering and scraping it moved away and he saw or thought he saw it go out of the door opening.
He lay on his side for a moment, then pulled a rasping breath in and held it, listening for the attacker to return. When it was apparent that the shadow wasn't coming back he felt the calf of his leg, where the pain was centered and spreading to fill the whole leg.
  His fingers gingerly touched a group of needles that had been driven through his pants and into the fleshy part of his calf. They were stiff and very sharp on the ends that stuck out, and he knew then what the attacker had been. A porcupine had stumbled into his shelter and when he had kicked it the thing had slapped him with its tail of quills.
  He touched each quill carefully. The pain made it seem as if dozens of them had been slammed into his leg, but there were only eight, pinning the cloth against his skin. He leaned back against the wall for a minute. He couldn't leave them in, they had to come out, but just touching them made the pain more intense.
  So fast, he thought. So fast things change. When he'd gone to sleep he had satisfaction and in just a moment it was all different. He grasped one of the quills, held his breath, and jerked. It sent pain signals to his brain in tight waves, but he grabbed another, pulled it, then another quill. When he had pulled four of them he stopped for a moment. The pain had gone from being a pointed injury pain to spreading in a hot smear up his leg and it made him catch his breath.
  Some of the quills were driven in deeper than others and they tore when they came out. He breathed deeply twice, let half of the breath out, and went back to work. Jerk, pause, jerk — and three more times before he lay back in the darkness, done. The pain filled his leg now, and with it came new waves of self-pity. Sitting alone in the dark, his leg aching, some mosquitoes finding him again, he started crying. It was all too much, just too much, and he couldn't take it. Not the way it was.
