Symptoms:
- Runny or stuffy nose
- Sneezing
- Sore throat
- Cough
- Mild fever
- Fatigue
Treatment: While there is no cure for the common cold, symptoms can be managed with rest, hydration, and over-the-counter (OTC) medications like acetaminophen for fever or pain relief. A humidifier can also help ease congestion.

Symptoms:
- Ear pain or tugging at the ear
- Difficulty hearing
- Irritability or fussiness
