A 40-year-old male presents with injury to his left hand by a nail gun. While at work, the patient accidentally shot himself with a nail gun. The nail went through pneumatic air hose tubing, his third finger, and his thumb, keeping them all connected. He immediately felt uncomfortable in his left arm, and, upon arrival to the emergency department (ED), complained of swelling in his left arm extending to his neck. He feels shortness of breath and “fullness” in his throat.
