How To Tell When Your Cold Has Become a Sinus Infection

As the temperatures drop here in Connecticut, New York and Massachusetts, the common cold is on the rise. The symptoms are no mystery: congestion and runny nose, cough, headache and perhaps a sore throat and mild fever. But sometimes that cold (or even allergies) can lead to a less common condition that shares many of the same symptoms: a sinus infection.
While treatment with antibiotics will do nothing to improve a cold, it could be necessary to clear up a sinus infection. That’s why it’s important to know how to tell the difference so you can seek care when it’s needed.
Here’s what you need to know…

What is a sinus infection?

The sinuses (also called nasal passages) are hollow cavities in the bones of the skull. They are located on either side of the nose, between the eyes, and in the lower center part of the forehead.
Normally, the sinuses are empty. But a cold virus or allergies can cause the tissue inside the sinuses to swell, causing that “stuffed up” feeling. This is called sinusitis. Sinusitis can cause excess mucous and fluid to become trapped within the sinuses. That mucous can become a breeding ground for germs and when it does, a sinus infection can occur.

Is a sinus infection contagious?

Sinus infections are not contagious, but the colds that can lead to a sinus infection are – so wash your hands frequently and cover your mouth with the inside of your elbow to prevent the spread of cold germs.
 

Cold symptoms vs. sinus infection symptoms

Colds and sinus infections share many of the same symptoms, including a stuffy and runny nose, sinus pressure, headache and feeling tired. But there are a few symptoms to watch for that may mean you’re suffering from a sinus infection and not just a cold. They are:

  • Severe pressure and pain in your upper jaw or cheekbones
  • A high or persistent fever
  • Thick yellow or green mucus draining from your nose or down the back of your throat (which is called postnasal drip)
  • Bad breath
  • Decreased sense of smell

The length of time you’ve been suffering with symptoms can also be an important clue. Cold symptoms will generally begin to improve in three to five days. If you find you’re still suffering after 10 days or longer, it’s likely that you’ve developed a sinus infection. If your symptoms improve and then suddenly get worse again, that’s another clue. This pattern suggests that what began as a cold or viral sinusitis has now developed into a bacterial sinus infection.
 

Sinus infection treatment and sinus pressure relief

If you’re suffering from a short bout of sinusitis – which is inflammation of the sinuses from a cold or allergies, but not necessarily infection – there are several things you can do at home to ease your sinus pressure symptoms. Use over-the-counter decongestants and saline nose spray to open up the nasal passages. Pain relievers like ibuprofen or acetaminophen can provide relief from sinus pain as well.
However, if your symptoms last more than a few days you should see a doctor for evaluation and treatment. If your cold or sinusitis has developed into a bacterial sinus infection, you may need antibiotics to treat it. Both adults and children can receive care for sinus infections at any of our PhysicianOne Urgent Care centers in Connecticut, Massachusetts or New York, 365 days per year. You can even check in online now at the center nearest you for a convenient appointment with minimal time in the waiting room.

"The overall care I received was excellent! I also appreciate your affiliation with Yale New Haven Hospital."

Patient
Derby, CT

"Throughout the visit I felt like the staff really cared. The Doctor took his time talking with me about my symptoms, and I felt like he listened to all my concerns and took that into consideration when recommending the right treatment. Thank you!"

Patient
Hamden, CT

"I had to take my son in for an ear infection following a sudden change in temperament at daycare. He was inconsolable the entire car ride but when we got there and by the time we left this care facility he was back to his normal happy go lucky little two year old boy. I highly recommend PhysicianOne Urgent Care."

Patient
Westwood, MA

"I wanted to take a moment to thank you for the attention you gave me last week. My son was started on antibiotics and ear drops. Within 24 hours he began to feel better. The poor kid had been going to school in tears because he was afraid of missing any more days, but feeling (and looking) just awful! He's not been able to even think about lacrosse practice, but thanks to starting him on antibiotics, he was thrilled to return to practice today."
