Not Just a Headache

Chronic CSF leaks, pain, unpredictability, daily function, and body trust

Over the past years, I have learned a great deal about a condition I once thought was a headache. That is often how it is described. A headache complication from epidural anesthesia. One item on a list of risks, usually mentioned quickly while you plan your birth. But for some patients, the reality can be much broader and more disabling.

Before writing more in this space about my evolving reflections, I wanted to share something a little different: a context and awareness piece about the condition that changed my life. This is written from my own experience with spinal CSF leaks, while leaving room for the fact that not every patient’s experience looks the same.

What can a CSF leak feel like?

For some people, a CSF leak can feel like your brain has become too heavy for your head and body. Like something that was once floating has started to sink, crushing everything beneath it. It can feel like nagging and debilitating pressure at the back of your head, pain through your neck and shoulders, and a strange downward force your body is constantly trying to resist.

Sound and familiar voices can become sharp and unbearable, as if they are entering too deeply into your brain. Vision can blur or double. The eyes can feel heavy. Ears can ring, muffle voices, or make your own voice echo inside your head.

Walking on stable ground can feel like walking on a rocking boat. A still room can feel like it is moving. The body can feel unsettled: heart racing, breath suddenly hard to catch, rest not fully restful. It may twitch, flutter, spasm, or glitch in ways that feel like your nervous system has started acting on its own.

And then there are the cognitive parts. Thinking can feel physically effortful. Words disappear. Multitasking becomes almost impossible. Even small choices can feel like your brain has to push through pain just to answer which shoes, or which drink.

Sometimes word loss can bring moments of laughter. I have asked for “the thing that sucks things” when I meant the vacuum, or moved an invisible joystick in the air when I couldn’t find the word wheelchair. Other times, symptoms feel less funny when the stakes are higher, though I sometimes can still laugh in retrospect.

Mornings, after a night spent flat, can make the first stretch upright almost entirely nonfunctional. The number of hours varies, but those early hours can feel like being pulled deep inside your own body, wrapped inside incessant head and sensory pain, while the world around you blurs into something you need to escape. In that state, you can be physically present with your family, but consumed by your symptoms, limiting sensory input, managing pain, and unable to hold a conversation or respond to the people you love most the way you want to.

Sometimes that means your child carefully chooses a book and sits gently beside you instead of on your lap, to avoid triggering more pain, and you still have to say no because even reading a toddler book is more than your body can handle.

What triggers pain? Is it predictable?

For many patients, symptoms are positional or triggered by certain movements and activities. A bend to grab something lower, a stretch to grab something slightly out of reach, lifting even a newborn, twisting, walking, or simply sitting upright for longer than your body can manage, can bring on a randomized combination of pain and neurological symptoms. The length and severity of the symptoms is also anything but predictable.

But the lack of predictability does not only show up in symptoms. Improvement is not always linear either.

Your body may improve, regress, improve again, and then regress without warning or pattern. Clinical progress may not feel like progress in daily life. You may have a better scan, a better procedure, or a leak closed in surgery, and still not be able to feel it in your body.

What it does to body trust

You stop trusting that you can walk safely.

You stop trusting that you can be upright without suffering.

You stop trusting that your arms will reliably have the strength to hold your child.

You stop trusting that your body will be available and present in life.

You stop knowing whether your body is warning you, or malfunctioning.

You begin facing which parts of daily life you can still do, which ones you can no longer do, and how many ordinary tasks now require another person’s hands.

So everything becomes a calculation. How long can I sit? How long can I stand? How far can I walk? Is there a place to lie down? How long can I look at a screen or hold a conversation? What happens if symptoms flare? What is the exit route?

Sometimes the dread begins before the symptoms do.

And still, you do things anyway. Because being sick does not mean you stop wanting to live.

What’s behind these symptoms?

This is about to get slightly technical, but stay with me if you are the curious type.

The brain and spinal cord are surrounded by cerebrospinal fluid, or CSF. This fluid cushions the brain and spine, helps them remain buoyant, and plays a role in nourishing and clearing waste from the central nervous system.

A spinal CSF leak happens when there is a tear or hole in the dura, the protective layer that holds this fluid around the brain and spinal cord. When CSF leaks out, the volume and pressure of the fluid system can become too low.

When a person is upright, gravity can make this worse. The brain may no longer be supported in the same way, which can lead to pulling, brain sagging downward in the skull, pressure on sensitive structures, irritation of nerves, and a wide range of symptoms.

This is why the classic symptom is often a positional “headache,” or head pain as many in the patient community call it. Often worse upright, better lying down. But for many patients, like myself, the experience is much broader. It can involve the eyes, ears, neck, spine, cognition, balance, nausea, and the nervous system as a whole.

Symptoms can vary in intensity and spread from mild to severely disabling. Some people remain able to function with modifications. Others may have extremely limited functioning and upright time. Some alternate between both states of functioning depending on the month, week, day, or hour, sometimes looking fine in selected moments while the adaptations remain invisible.

So why can’t we just fix it?

Many CSF leaks resolve with conservative treatment, such as rest, or after an epidural blood patch. Some patients improve relatively quickly and return to normal life.

But for a subset of patients, like me and many others, it is not as simple. A leak may not seal after a blood patch. Improvement may happen briefly and then fade. The leak may reopen, be difficult to find on imaging, or more leaks may still be present. Some need multiple procedures to fix multiple leaks. Some need one or more surgeries. Some have symptoms that persist for months, years, or, in rare cases, decades.

There is no single path that fits every patient. Complex and chronic CSF leak care and treatment often requires cross-disciplinary specialists, imaging, procedures, time, rest, and a lot of uncertainty. And as a CSF leak patient navigating all this, you are often forced to live without clear answers and with a deep lack of predictability.

It is not only the pain. It is the loss of trust in your own body and your ability to plan for your life that make this condition the hardest.

This piece only covers the illness context. I hope to write more about the life that moves in around it: the adaptations, the medical journey, and the small ways a family learns to keep going.
