Is it Covid or a cold/allergy? 6 days ago, I had a runny nose and 2 days later, swelling in my tonsils. What should I do?

It is important to monitor your symptoms and seek medical advice if they worsen or if you develop a fever. Rest, drink plenty of water, and isolate yourself if you are coughing to prevent spreading any potential illness to others. It is also a good idea to take care of yourself and get plenty of rest to help your body recover.
