Feeling of something stuck in the throat (known as globus) and increased mucus in nose when eating—are frequently caused by post-nasal drip, allergies, or acid reflux. Because you can still eat and drink normally, it is likely not a physical blockage, but rather inflammation or muscle tension in the throat.
Next Steps
Treatment you can do are:
Nasal Irrigation, hydration, gargling with saline water, avoid eating for at least 3 hours before bed, minimize spicy foods, caffeine, and alcohol, use a humidifier while sleeping, to keep your nasal passages and throat moist, for allergy or post-nasal drip take antihistamines or nasal steroid sprays.
