Don't worry nothing is wrong with you! your swollen tonauge might be friend allergies and omg I have chapped lips on the sides of my lips too!:) haha I put cortisone on them at night before I go to bed and like 3 days later they are gone! My doctor persribed this hope I helped!:)

Nothing is wrong with you, apply Vaseline you could get it at a drug store.
Sounds like you have a cold. Your lymph nodes get swollen when you have a cold. It also sounds like you are having labored breathing due to your cold (congestion), which makes your lips chapped. If it doesnt get better or gets worse within 3 days, speak to your PCP.
Feel better, have chicken soup! :) and rest!
