Hello,
I understand your concern. The symptoms you describe – feeling hot after meals, burning sensation in mouth/ear, and intermittent swelling in the neck – can be due to several possible causes such as acid reflux, food-related allergy/intolerance,
thyroid or salivary gland issues, or even lymph node swelling due to infection/inflammation.
Since this has been ongoing for a month and is affecting your daily life, it is important that you get examined in person. A physical examination and some tests like thyroid profile, ultrasound of the neck, and possibly an ENT evaluation will help identify the cause.
Next Steps
Avoid spicy/oily food, alcohol, and smoking until reviewed.
• Maintain a food diary to see if symptoms worsen with certain foods.
• Book an appointment with an ENT specialist or a physician soon for proper evaluation.
