What Happens If You Can't Stop Sneezing?

An inability to stop sneezing can cause excessive nasal secretions, make symptoms worse if untreated, and make it difficult to concentrate on other activities. People with excessive allergy symptoms such as sneezing can suffer from conditions including hypertension and diabetes, so symptoms must be treated. In some extreme cases, excessive sneezing causes extreme pain and can be emotionally disruptive.

If nasal secretions from sneezing are green or yellow, and symptoms last 3 to 14 days, sneezing may be indicative of a cold, according to Best Health magazine. If symptoms last longer and nasal secretions are clear, the magazine indicates that sneezing could be symptomatic of allergies.
