Tonsils can vary in size, so don't worry about that. As for difficulty in swallowing, or sense of food sticking in the throat, it may be due to acidity sometimes. Take warm soft foods, gargle with warm water and take antacid syrup. Stay at home.
Next Steps
If throat discomfort worsens, or you get fever, cough or breathlessness, please get yourself tested for covid as a precaution.
