Many different upper respiratory infections can bring about the same unpleasant symptoms, like a runny nose, fever, chills and coughing. Most of the time it’s just a common cold — but knowing the difference can save you a trip to your doctor or get you on the right treatment path quickly.
The sudden onset of wheezing, shortness of breath, tightening of the throat or a fever that doesn’t respond to over-the-counter medication are all cause for concern.
“If the symptoms worsen or last longer than 10 days, you should get checked out by a professional,” says Julio Romero, MD, family medicine physician at Scripps Coastal Medical Center Solana Beach. “The key is, you should get progressively better.”
However, if your symptoms are less severe, simply stay home, rest up and hydrate.
“You can use over-the-counter fever/pain reducers, expectorants, a saline gargle or a humidifier to treat your symptoms at home,” Dr. Romero says.
Learning the differences between these upper respiratory tract infections can help you understand when to stay home, when to visit the doctor and what else to watch out for.
