A sore throat is right up there with a stuffy or runny nose on the list of common symptoms. But common doesn’t equal harmless. Read on to learn more.

Sore throats are among the most common symptoms a person can experience. But while most of the time there’s nothing to worry about, there are certain times when it’s best to visit your primary care physician.

A sore throat may be a symptom of the flu. If the pain is persistent and accompanied by heartburn, it may be a signal of gastrointestinal reflux disorder GERD, in which stomach acids back up in your esophagus.

In rare cases, a sore throat may be a sign of throat, tongue or voice box cancer. If you suspect you have any of the above, make an appointment to see your doctor.

Acid reflux can be treated through dietary and lifestyle modifications, medications — usually proton pump inhibitors (PPIs), and in some cases, surgery is a treatment option,” said Michael Johns, MD, professor of Clinical Otolaryngology-Head and Neck Surgery at Keck School of Medicine and director of the USC Voice Center of the USC Caruso Department of Otolaryngology – Head and Neck Surgery of Keck Medicine of USC. “Long-term reflux can cause laryngeal ulcers or granulomas, vocal fold scarring, pneumonia, Barrett’s esophagus, and in some cases esophageal or throat cancer.”

If you have a fever and general aches and pains along with that sore throat, you may have strep throat, particularly if you have been around children or anyone else with the contagious condition. Getting treatment is essential if you have strep throat because the inflammation can spread to surrounding lymph tissue and your tonsils, potentially obstructing your airways and making it hard to breathe.

In extreme cases, the bacteria can get into your bloodstream and cause infections in your heart valves, which can be life threatening. It can also spread to your other organs, such as the liver, brain and kidneys. The good news is that strep is easy to diagnose with a throat culture and responds well to treatment with antibiotics.

If it’s your child who has a sore throat, it may be a symptom of tonsillitis, a viral or bacterial infection that typically is seen in children from preschool age to mid-teens. Tonsillitis is rare in adulthood.

Other symptoms of tonsillitis are red, swollen tonsils; white or yellow patches on the tonsils; pain when swallowing and fever. Tonsillitis usually is caused by a virus, which means it should clear up on its own, but if your child’s symptoms haven’t improved in 48 hours or he or she is experiencing the aches and pains that go along with strep, your child should see your pediatrician.

But most of the time, a sore throat, while painful and inconvenient, is nothing to be overly concerned about. Sore throats often are a symptom of hay fever or allergies. They also are common in the winter, when the air is dry. If you sleep with your mouth open or snore, you may wake up with a sore throat, and the solution may be as simple as a humidifier, or, if you were at a concert or loud party or club the night before, chances are good you strained your vocal chords.

Your best bet in these cases is to practice self care, including drinking plenty of hot tea with honey and sucking on throat lozenges. Your sore throat is most likely caused these environmental factors or a viral infection that doesn’t require antibiotics and should start to get better on its own in a few days. If you find you’ve lost your voice, rest your vocal chords and try not to whisper.
