I'm sorry to hear that you're experiencing coughing at night and the sensation of something stuck in your throat. This can be uncomfortable and concerning.

Based on your description, one possible cause is acid reflux or gastroesophageal reflux disease (GERD). This condition occurs when stomach acid flows back into the esophagus (food pipe), irritating the lining and causing symptoms like coughing, throat discomfort, and a feeling of something stuck. The fact that drinking water helps suggests that the irritation might be temporarily relieved by washing down the acid or mucus.

Possible causes and contributing factors include:

• Acid reflux, especially when lying down
• Postnasal drip from allergies or sinus issues
• Throat irritation or mild infection

To help prevent and manage these symptoms:

• Avoid eating large meals or heavy, spicy, or acidic foods close to bedtime.
• Elevate the head of your bed slightly to reduce acid reflux during sleep.
• Avoid caffeine, alcohol, and smoking, which can worsen reflux.
• Stay hydrated but avoid drinking large amounts of water right before sleeping.
• Maintain a healthy weight, as excess weight can increase reflux risk.

Since persistent coughing and throat discomfort can have various causes, it is important to consult a gastroenterologist or an ear, nose, and throat (ENT) specialist. They can evaluate your symptoms thoroughly, possibly recommend tests, and provide appropriate treatment.

If you experience worsening symptoms such as difficulty swallowing, chest pain, or breathing problems, seek medical attention promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
