Common Cold

Symptoms

Symptoms of the common cold usually begin 2 to 3 days after infection and often include

  • Mucus buildup in your nose
  • Difficulty breathing through your nose
  • Swelling of your sinuses
  • Sneezing
  • Sore throat
  • Cough
  • Headache

Fever is usually slight but can climb to 102 degrees Fahrenheit in infants and young children. Cold symptoms can last from 2 to 14 days, but like most people, you’ll probably recover in a week. If symptoms recur often or last much longer than 2 weeks, you might have an allergy rather than a cold.

Colds occasionally can lead to bacterial infections of your middle ear or sinuses, requiring treatment with antibiotics. High fever, significantly swollen glands, severe sinus pain, and a cough that produces mucus may indicate a complication or more serious illness requiring a visit to your healthcare provider.
