What's the difference between a cold and the flu?

Not sure what your symptoms really mean? Learn the difference between a cold and the flu, available treatments for both and when to see a doctor.

A cold normally starts out with a tender throat and a sore feeling when swallowing. Your head may begin to ache and a stuffy or runny nose may develop. You'll feel lethargic and may develop a cough into the fourth day of the cold. The cough may be dry or productive if mucus develops in the throat and lungs. A cold can last from seven days to two weeks depending on the severity of the virus.

The flu usually hits hard with symptoms that can resemble a very bad cold. Flu symptoms that aren't normally associated with a cold include a fever and muscle soreness. While the flu may not last as long as a cold, the symptoms may leave you feeling weak for weeks. The flu can also develop into pneumonia in the elderly or young children, which is why it's important to receive a flu shot annually, especially if you are regularly in the company of people who may be immunocompromised.

The recommended home treatment is similar for both the cold and flu. Drink eight to 10 glasses of water daily to help rid toxins from the body. Drink warm beverages like tea to soothe a sore throat and inhale the steam to open nasal passages. Medications like decongestants and pain relievers can be used for both a cold and the flu. To reduce a fever, take ibuprofen or a medication suggested by your doctor.

Normally there is nothing your doctor can do to make symptoms end any faster if you're suffering from a cold or the flu. However, there are instances in which you should see a doctor. A cold can graduate into a bacterial sinus infection, which causes facial pain. A severe sore throat may indicate strep throat, while heaviness in the chest and coughing may indicate bronchitis. If a cold or flu lasts longer than normal or your symptoms are getting worse, see your physician who can determine the right course of treatment.

Knowing the difference between a cold and the flu may help when treating symptoms. Regardless of whether you think you have a cold or the flu, take care of yourself.
