Hi, Looking at your history,you might be suffering from Laryngospasm. Laryngospasm is an uncontrolled/involuntary muscular contraction (spasm) of the vocal folds. The condition typically lasts less than 60 seconds, but in some cases can last 20-30 minutes and causes a partial blocking of breathing in, while breathing out remains easier. It may be triggered when the vocal cords or the area of the airway below the vocal folds detects the entry of water, mucus, blood, or other substance. Laryngospasm may also be a complication of surgery. Anesthesia used during the surgery can irritate the vocal cords,as might have happened in your case. Laryngospasm may be associated with different triggers, such as asthma, allergies, exercise, irritants (smoke, dust, fumes), stress, anxiety or commonly gastroesophageal reflux disease (GERD). If GERD is the problem,then you may be suffering from other symptoms like burning pain the stomach/Central chest region or throat,indigestion,fullness in your stomach. Treating this condition by proton pump inhibitors such as Pantoprazole and Prokinetic agents like Domperidone can help manage laryngospasm. Avoid common heartburn triggers, such as fruit and fruit juices, caffeine, fatty foods, and peppermint. Eat smaller meals, and stop eating two to three hours before bedtime. If you smoke, quit. Also, limit alcohol consumption. Raise the head of your bed a few inches by putting wood blocks under the bedpost. Hope I have answered your query. Let me know if I can assist you further.
