Hi, i have had swollen tonsils and feels like my ears are plugged for awhile now, but no pain. allergies or infection?

Eustachian tube : A small tube goes from the back of your nose to your ears. = eustachian tube. When nose is plugged, tube gets blocked & gives you painful pressure in your ear(s). If pain persists, ear can become infected. If you have persistent/worsening pain, especially with fever, you should see a doc. Reduce your ear pain by treating allergies if y, drinking hot tea, gently blowing nose, maybe decongestant.
