Is Nasal Discharge Clear Fluid a Sign of Cerebrospinal Fluid Leakage?

Running a clear nose can be caused by upper respiratory infections such as colds, but it can also be due to cerebrospinal fluid leakage. In this case, it is important to distinguish it from a common cold. The first step in determining whether the clear nasal discharge is cerebrospinal fluid is to learn how to identify its characteristics. Cerebrospinal fluid is typically characterized by being colorless and transparent, similar to clear water, and without impurities. In contrast, nasal discharge caused by a cold may be slightly viscous and contain impurities from the nasal cavity and external substances. Cerebrospinal fluid leaks directly from the spinal cord, resulting in a very clear and non-viscous texture.

If cerebrospinal fluid is leaking from the nose, the amount of discharge may decrease when lying down or tilting the head backwards, which is related to the location of the leak. The amount of cerebrospinal fluid leaking depends on the position of the leak; if the leak is higher when lying flat, no fluid will leak out, while if the leak is lower, cerebrospinal fluid will continue to leak. Additionally, the direction of the leak can affect the flow of the fluid; for example, if lying on the left side, the fluid may leak out of the left nostril, and if lying on the right side, it may leak out of the right nostril.

In some cases, not only the nose but also the ears may discharge clear fluid, which is also cerebrospinal fluid due to a cerebrospinal fluid leak into the ears. This can occur in cases of brain trauma, where fragments may damage the structure of the ear, allowing cerebrospinal fluid to leak out through the ear canal.

If a cold causes persistent clear nasal discharge, several remedies can be tried to alleviate the symptoms:

1. Apply ginger to the bottom of the feet: Placing ginger on the bottom of the feet can be effective for relieving nasal congestion. Finely chopping ginger and applying it with a plaster to the bottom of the feet before going to sleep may help reduce nasal discharge the next day.

2. Consume scallion soup: Nasal discharge and congestion can also be caused by viral infections. Scallions, which have antibacterial and detoxifying properties, can be used as a treatment. Clean and cook the white part of the scallion, then add some rock sugar. Drinking this soup for a few days may help reduce nasal discharge.

3. Rinse the nose with diluted salt water: Keeping the nasal cavity clean can help reduce nasal discharge. Using diluted salt water to rinse the nose can eliminate viruses and bacteria, promoting a clearer nasal passage.

4. Apply a warm compress to the nose: If the nasal discharge is viscous and causing congestion, applying a warm compress to the nose can help. The heat will cause the nasal mucosa to contract, allowing for easier passage of nasal discharge.
