When A Runny Nose Is Brain Fluid Leaking: Here Is What To Do

It’s not snot. It’s leaking brain fluid.

That’s what Greg Phillpotts learned after suffering from a runny nose for 5 years, as described by Josh Chapin for ABC 11 Eyewitness News. Here’s a Tweet from Chapin:

It turned out that Phillpotts was not experiencing constant allergies as he had been told previously. Instead, cerebral spinal fluid (CSF) was leaking out into his nose. CSF is a fluid that surrounds your brain and spinal cord, cushioning, protecting, and supporting those parts of the body. CSF is one of the reason your brain doesn’t land with a thud every time you do a jumping jack or listen to Metallica. Normally, the membranes keep the CSF contained, a bit like a big water balloon around your brain and spinal cord. However, anything that may damage the membranes, such as a head injury, surgery, or a tumor, may leave a hole though which the fluid can leak out, potentially into your nose or ear.

Here’s a TODAY show segment about another person who had a somewhat similar experience:

As you can see, such a condition can go misdiagnosed for years. That’s because “brain fluid leaking” is usually not the first thing you think about when you have a runny nose. Usually, it’s a cold, the weather, allergies, cheap cologne, watching too many rom-com movies, or that darn cat. After all, the condition is very rare. However, consider the possibility of a CSF leak if you find the following:

  • The fluid only comes out of only one nostril or one ear. Allergies tend to be more equal opportunity and affect all of your nasal passages or both your ears.
  • The leakage lasts for a long time. A cold or the effects of a romantic comedy should not last for several years at least not continuously.
  • Tilting your head forward or straining makes the drainage worse. This could make toilet trips particularly fun.
  • The drainage started after head trauma or surgery. There isn’t always a clear cause of the defect or drainage but check what you were doing before the drainage started.
  • The drainage doesn’t change with the seasons or location. Allergy symptoms may approve the further you stay away from Mr. Bigglesworth but a CSF leakage won’t.
  • The volume of drainage is more than you would expect from a cold or allergies. If you wake up and find your shirt or pillowcase soaked that is more than you may expect from allergies or an infection.
  • You have accompanying headaches or changes in vision or hearing. A classic symptoms is a headache that improves when you lie down. Of course, such symtpoms can occur in other conditions. But such symptoms should warrant further exploration.

As the Cleveland Clinic describes, your doctor can test for a CSF leak by having you lean forward to see if the drainage increases, using a scope to examine your nasal passages, ordering imaging like a CT or MRI, and testing the fluid to see if it resembles CSF. If a CSF leakage has started recently, your doctor may recommend a more conservative approach, giving the defect time to heal on its own. This means staying in bed for a week or 2 and avoiding movements that may keep the defect from healing coughing, sneezing, straining, or laughing. Therefore, you may want to take stool softeners and limit your television watching to C-SPAN.

If conservative approaches don’t resolve the leakage, surgery may be in order. Depending on where the defect is located, your doctor may be able to fix it with using a scope.

You don’t want to let a CSF leakage go on without fixing it. As one of the surgeons says on this segment of the television show Botched, “brain fluid coming out of the nose is a major concern”:

There are very few sentences with the words “brain” and “coming out of the nose” that should not raise concern. Any defect in the membranes surrounding and protecting the brain and spinal cord can serve as a revolving door for bacteria and other microbes. Such microbes can cause very serious and life-threatening infections such as meningitis. Moreover, CSF leaks can progress to more debilitating symptoms such as severe headaches or be the sign of a more serious problem such as a tumor.

As KidsHealth has pointed out, there’s an old joke that says if your nose is running and your feet smell, you must be upside down. Well, if your nose keeps running for weeks or months, see your doctor because something doesn’t smell right.
