Orthostatic Headache and POTS: Why Your Head Hurts When You Stand Up

What Is an Orthostatic Headache?

Orthostatic means related to standing upright. An orthostatic headache follows your posture: it builds after you get up and eases once you lie flat again. That link to posture is the clue.

One known cause is spontaneous intracranial hypotension (SIH), where cerebrospinal fluid (CSF) leaks out and the fluid cushioning the brain runs low. A 2026 case report calls SIH "an uncommon and frequently under-recognized cause of orthostatic headache, resulting from spontaneous cerebrospinal fluid (CSF) leakage." The IIH guideline lists headache from low CSF pressure as a separate type (Mollan, 2018).

Why Does a Spinal Fluid Leak Cause a Headache When You Stand Up?

In the clinic's view, too little pressure in the head is the opposite of intracranial hypertension, and it usually comes from a CSF leak. Leaks come in 2 types. Cranial leaks sit in the head, and one common feature is clear fluid leaking from the ears or nose. Spinal leaks tend to present more with headaches.

Those headaches are usually worse when you stand up. As you stand, you create vacuum pressure that pulls down on the system, and pain in the head follows. Bearing down, coughing or straining on the toilet can make the headache worse too, because anything that changes that pressure quickly can bring one on.

The 2026 case report describes a 39-year-old woman whose headache was "markedly worse on standing and relieved by lying flat." Her MRI showed "diffuse pachymeningeal enhancement and an extensive spinal longitudinal epidural CSF collection," which means the lining around the brain stood out on the scan and fluid had collected along the spine. That's 1 case, so it shows what the pattern can look like and says nothing about how common it is.

A headache that starts suddenly and is extremely painful, or comes with weakness or numbness, confusion, vision loss, or a stiff neck and high temperature, needs emergency care (NHS).

Is a Headache When Standing Up a Sign of POTS?

It can be. Headache is common in POTS, and POTS symptoms are defined as brought on by standing and relieved by lying down. The 2021 POTS consensus names headache among the other persistent symptoms people with POTS can have (Vernino, 2021). How many POTS headaches follow posture hasn't been measured.

A 2026 clinical review lists 3 parts to POTS: "chronic orthostatic intolerance (bothersome symptoms brought on by upright posture, and relieved by lying down)," a heart rate rise on standing "greater than 30 beats per minute in adults," and no orthostatic hypotension. The 2021 consensus sets the line at 30 or more within 10 minutes of standing, or 40 or more for ages 12 to 19 (Vernino, 2021).

In our team's view, when POTS brings symptoms like dizziness, blurred vision, ringing in the ears or headaches, the blood pressure changes are often happening less in the body and more in the head, and a normal blood pressure reading can miss changes in the brain. Our team sees the heart rate rise in POTS as the body working to hold brain blood flow steady upright, and our page on OCHOS (orthostatic cerebral hypoperfusion syndrome) explains how brain blood flow is measured when heart rate and blood pressure look normal.

Can You Have a Spinal Fluid Leak and POTS at the Same Time?

A 2026 study from a single center in Seoul checked autonomic function in 34 people with SIH. It reports that "postural orthostatic tachycardia syndrome was the most frequent orthostatic abnormality, observed in 12 of 34 (35.3%) patients." The authors note that "SIH often presents with orthostatic symptoms that overlap with autonomic disorders," and that how often autonomic problems occur in SIH remains "poorly characterized."

With 34 patients at 1 center, the study shows the overlap exists and can't tell you how common it is elsewhere. If an upright headache is new, came on suddenly, or gets worse when you cough or strain, ask your doctor whether a spinal fluid leak has been ruled out. The Seoul study looked the other way, at POTS among people with leaks, so it can't say how often a leak sits behind a POTS headache. If you have a known leak, it's worth checking how your heart rate responds when you stand.

What Else Can Make Your Head Hurt When You're Upright?

Pressure can also run high, and a headache from intracranial hypertension is typically worse lying down. Our page on intracranial hypertension covers that condition and how it overlaps with POTS. Migraine has its own pattern, and migraine as a neurological event covers how our team approaches it.

Dizziness in POTS overlaps with other conditions as well. A 2026 review written for ENT clinics notes that POTS can look like vestibular migraine, a migraine type where dizziness leads, and persistent postural perceptual dizziness (PPPD). Headache is one of several symptoms that can come with being upright, and our guide to orthostatic intolerance walks through the rest and how orthostatic hypotension, POTS and OCHOS differ. For how the criteria split, see orthostatic hypotension vs POTS.

What Helps an Upright Headache?

What helps depends on the cause, so finding it comes first. For POTS, medications can help and can serve as a bridge, but they have a ceiling, and our team looks for what's driving the upright symptoms.

How Do You Find Out What's Driving It?

The pattern of the headache narrows the search. Pain that follows your posture and flares when you cough or strain points toward pressure. The NHS advises an urgent doctor's appointment for a headache made worse by coughing, sneezing or bending down, and in the 2026 case it was the MRI that showed signs of a leak. When upright headaches come with a racing heart, our team tests how brain blood flow, breathing and heart rate respond as you go from lying down to standing, to see which part of the system is carrying the most.
