Signs and symptoms

One of the most common symptoms of a spinal CSF leak is a positional/orthostatic headache.  This means that the patient feels partial or complete relief of the headache when he or she lies down and the patient’s headache worsens considerably when the patient is upright. 

On occasion, the headache may not be orthostatic.  Sometimes, it just starts over the course of hours to days and just does not go away.  This is called a New Daily Persistent Headache.

Key Notes

“The headache feels like a brick is pushing my brain down to my throat”  - Anonymous CSF leaker.

  • In some cases, the positional aspect of the headache can fade away with time or may not be very obvious to some patients. 

  • In some cases, it can take hours for the symptoms to be alleviated once lying down.

  • Some patients with CSF leaks experience what is known as ‘end of the day or second half of the day headaches, after hours of being upright.

  • Coughing, sneezing, laughing, bending, crying (known as valsalva activities) can worsen the symptoms.
