With a sneeze, tremendous air pressure is created in the lungs which ideally should be released out the mouth... but if internalized to prevent release out the mouth, can cause immense pressure to buildup internally which may cause significant damage ranging from minor to severe requiring hospitalization.
Although most of the time, no adverse health consequences occur, here are some of the reported damage that has happened by stifling a sneeze:
• Breaking the cartilage around the voicebox
• Cervical pain
• Facial fracture
• Rupturing the eardrum
• Rib fractures
• Eye damage
• Vision damage
• Spinal injury
• Arterial rupture
• Hematoma formation in the neck and other locations
• Vocal cord damage
So do as Elsa of Frozen fame would say/do... "Let it go!!!"
