Dr. Kelso asks Dr. Murphy ("Nervous Guy") what the presentation of Ludwig's Angina is. As usual, Dr. Murphy is unable to answer. Ludwig's Angina is an inflammation of the tissues of the floor of the mouth, under the tongue. It is dangerous because the swelling can block the airway. Symptoms include breathing difficulty; confusion or other mental changes; fever; neck pain; neck swelling; redness of the neck; and weakness, fatigue, or excessive tiredness. It presents itself as redness and swelling of the upper neck, which may reach to the floor of the mouth; the tongue may be swollen or out of place.
