When you wake up sneezing, coughing, and have that achy, feverish, can’t move a muscle feeling, how do you know whether you have cold symptoms or the flu?
It’s important to know the difference between flu and cold symptoms. A cold is a milder respiratory illness than the flu. While cold symptoms can make you feel bad for a few days, flu symptoms can make you feel quite ill for a few days to weeks. The flu can also result in serious health problems such as pneumonia and hospitalizations.
What are common cold symptoms?
Cold symptoms usually begin with a sore throat, which usually goes away after a day or two. Nasal symptoms, runny nose, and congestion follow, along with a cough by the fourth and fifth days. Fever is uncommon in adults, but a slight fever is possible. Children are more likely to have a fever with a cold.
With cold symptoms, the nose teems with watery nasal secretions for the first few days. Later, these become thicker and darker. Dark mucus is natural and does not usually mean you have developed a bacterial infection, such as a sinus infection.
How long do cold symptoms last?
Cold symptoms usually last for about a week. During the first three days that you have cold symptoms, you are contagious. This means you can pass the cold to others, so stay home and get some much-needed rest.
If cold symptoms do not seem to be improving after a week, you may have a bacterial infection, which means you may need antibiotics.
Sometimes you may mistake cold symptoms for allergic rhinitis (hay fever) or a sinus infection. If cold symptoms begin quickly and are improving after a week, then it is usually a cold, not allergy. If your cold symptoms do not seem to be getting better after a week, check with your doctor to see if you have developed an allergy or sinusitis.
What are common flu symptoms?
Flu symptoms are usually more severe than cold symptoms and come on quickly. Symptoms of fluinclude sore throat, fever, headache, muscle aches and soreness, congestion, and cough. Swine flu in particular is also associated with vomiting and diarrhea.
When do I call the doctor with flu or cold symptoms?
If you already have flu or cold symptoms, it’s important to call your doctor if you also have any of the following severe symptoms:
- Persistent fever: A fever lasting more than three days can be a sign of another bacterial infection that should be treated.
- Painful swallowing: Although a sore throat from a cold or flu can cause mild discomfort, severe pain could mean strep throat, which requires treatment by a doctor.
- Persistent coughing: When a cough doesn’t go away after two or three weeks, it could be bronchitis, which may need an antibiotic. Postnasal drip or sinusitis can also result in a persistent cough. In addition, asthma is another cause of persistent coughing.
- Persistent congestion and headaches: When colds and allergies cause congestion and blockage of sinus passages, they can lead to a sinus infection (sinusitis). If you have pain around the eyes and face with thick nasal discharge after a week, you may have a bacterial infection and possibly need an antibiotic. Most sinus infections, however, do not need an antibiotic.
