However, since you feel you did not jam into the door too hard, if you develop nausea, vomiting, excess sleep, severe headache, difficulty in walking and balance, tremors, seizures, vision problems, ringing in ears etc then consult a doctor immediately. These
symptoms develop if there is a brain
injury or bleed. Otherwise this burning sensation will go in a few days. Also, if the area of burning sensation enlarges, or spreads, or sensation worsens, then consult a doctor immediately. Take care!
