You Might Have More Than A Migraine If…


High-Pressure Headaches
Those that suffer from high pressure tend to feel pressure behind the eyes (often mistaken for sinus headaches) and report feeling like their “head is going to explode” from the pressure. High-pressure headaches are generally characterized by being worse when laying down – often awaking in the middle of the night or first thing in the morning with a headache, and the headache tends to dissipate to some degree after being upright for a period of time (and that period of time is different for everybody). Caffeine generally exacerbates high-pressure headaches.

Low-Pressure Headaches
Those that suffer from low-pressure headaches tend to report feeling like there is an invisible pressure pushing down from the top of the head, often making it feel like your “head is going to implode.” Low-pressure headaches are characterized by being worse when upright and relieved by laying down. Low-pressure headaches are typically a sign of a cerebrospinal fluid leak (CSF Leak). The longer that the leak has existed, the less obvious the positional element is – meaning the patient can be upright longer before they feel the pressure at the top of their head, and they tend to need to lay down longer before getting any measure of relief. Caffeine often helps relieve low-pressure headaches.

Occipital Headaches
Chiari headaches are felt at the occiput – at the base of the back of the skull and upper neck. They are generally tussive in nature, where they are exacerbated by valsalva maneuvers, which generally include: coughing, sneezing, heaving, laughing hard, or bearing down (like with a bowel movement or childbirth). These maneuvers reduce cardiac output (the amount of blood coming from the heart with each heartbeat), which in turn affects the attempted flow of cerebrospinal fluid, and it increases vagal stimuli.

Connecting the Three Headaches

  • Untreated high pressure can cause cranial leaks (which leads to low pressure) – often accompanied by cerebrospinal fluid leaking through the nose or ears.


  • CSF leaks can sometimes seal on their own leading to rebound high pressure (which is temporary) or continued high pressure if they originally had high pressure.



  • Untreated low pressure can cause the brain to sag and as it sags the cerebellar tonsils can get lodged into the foramen magnum where it blocks the flow of cerebrospinal fluid, leading to occipital headaches (often diagnosed as a Chiari 1 Malformation).


  • Untreated spinal leaks can create a suctioning or pulling down effect where the cerebellar tonsils can get lodged into the foramen magnum where it blocks the flow of cerebrospinal fluid, leading to occipital headaches (often diagnosed as a Chiari 1 Malformation).




Major Problem Regarding Our Diagnoses & Treatment Options:

  1. Doctors and radiologists alike, tend to see the herniated tonsils and assume a small posterior fossa.
  2. Most do not check for high pressure or low pressure, even when directly asked and symptoms are present.
  3. When a posterior fossa decompression is finally offered, the high or low pressure is often left untreated which leads to a failed decompression.
  4. By the time sufferers get a name to go with their symptoms, we jump at the opportunity for relief.



The “Bobblehead Sensation” – When It Feels Like Your Neck Can No Longer Hold Up Your Head

While most of us experience this feeling either intermittently or continuously, it is generally related to structural instability issues:



  • Cervical Instability (also known as Sub-axial Instability, SAI) involves hypermobility of the C2/C3 to the C7 intervertebral discs. This condition (like most conditions involving the cervical spine) is a major cause of muscle spasms (in the neck and throughout the body at any point below the disc issues. When these neck spasms occur, they can cause the “Bobblehead sensation” where it feels like your neck can no longer hold up your head. This disc degeneration can lead to paralysis as discs compress the spinal cord.

Bridges are built as a means to assist people in getting over the things that obstruct their path. We are constantly facing obstacles when it comes to our health, so we decided to build a bridge! Chiari Bridges is a non-profit network built by Chiarians for Chiarians. Our goal is to provide information, substantiated by published studies, in a way that is easy to understand. We encourage readers, to not only read our articles, but look up every study for themselves and read that too. Print it out and sit down with a highlighter; read it as many times as necessary until you understand; then use it to talk to your doctors. Our doctors are under no obligation to read our articles, but they should be willing to read officially published studies from journals, especially those specific to their profession. As many of our authors are patients as well, all authors sharing original pieces will be writing under pseudo-ghost names, to protect them from being black-listed by their doctors. Chiari Bridges is not affiliated with any physician or medical group. You should in no way use this site as a replacement for diagnosis, treatment, or medical from a qualified medical professional. The information provided on our website is strictly for educational purposes, in order to help further the understanding of Chiari, and its associated conditions. Our goal is to share our collective experiences and the information we have gathered, with those in need of answers, that it may increase your knowledge and guide you in conversations with your doctors.
