Don’t Ignore That Sore Throat: When to Get Tested for Strep
Do you have a sore throat that isn’t going away on its own? Is the pain sudden and intense? Read on to learn when your sore throat might require treatment for a bacterial infection.

Everyone gets a sore throat now and then, and you know the drill—the discomfort in the back of the throat, the scratchiness, and the pain. You feel run-down, maybe a little bit achy. You might assume it’s just the beginning of a cold that will pass in a few days. 

Most of the time, a sore throat is caused by a virus that goes away on its own, but sometimes what feels like an ordinary sore throat could actually be a highly contagious bacterial infection that needs prompt treatment to avoid complications.

To help you tell the difference between the two, we asked our expert at North Tex MedCare Clinic & Urgent Care, Dr. Frank Lee, when your sore throat warrants a visit to the doctor’s office.

What exactly is strep throat

Strep throat is an infection of the throat and tonsils caused by the group A streptococcus bacteria. Unlike a viral sore throat, which often comes with coughing, sneezing, and a runny nose, strep tends to hit suddenly and focus primarily on the throat and tonsils.

Because it’s bacterial, your immune system needs help fighting it off, which is why antibiotics are necessary.

Strep throat symptoms to look for 

While many sore throats are viral, specific symptoms can point to a bacterial infection, such as strep throat.

Sudden onset of severe throat pain

A sore throat caused by a cold usually builds up gradually. Strep throat, however, often starts abruptly and causes severe pain when swallowing. You may notice your tonsils are swollen and red, and you might even see white patches or streaks of pus in the back of your throat.

Fever, nausea, or body aches

It’s common to have a fever with a sore throat. However, if the fever is high and doesn’t improve on its own, it could mean your immune system is fighting a bigger threat than the common cold virus.

Tiny red spots and rashes

If you look in your mouth and notice tiny red spots, they could be caused by toxins released by bacteria and by your immune system’s reaction to them. 

Get tested to avoid complications

Prompt treatment is essential if you suspect strep throat. Antibiotics stop the bacteria from spreading to the joints, nervous system, and heart. A quick test is enough to determine whether a virus or bacteria cause your symptoms. If we catch it early, we can easily treat strep throat with antibiotics
