Positional headaches tend to get worse when you stand up. They can be caused by several things, including dehydration or a cerebrospinal fluid leak.
A positional headache is a type of headache that gets worse when you stand up. The pain tends to subside once you lie down. They’re also known as orthostatic headaches or postural headaches.
These headaches may be a sign of problems with:
- your blood pressure regulation
- a cerebrospinal fluid (CSF) leak
- a brain tumor
The diagnosis is not always straightforward because diagnostic signs are often not apparent on tests. It may take some time for your healthcare provider to find the cause of your postural headaches.
Read on to learn more about the other symptoms of a positional headache and how they’re treated.
The main symptom of a positional headache is pain in your head that’s worse when you stand up. In addition, the pain is often more severe in the back of your head and gets worse throughout the day. You should feel relief when you lie down.
If your positional headache is caused by a CSF leak, you might also notice:
- clear liquid or blood coming out of your ears or nose
- vision problems
The CSF in the meninges cushions and protects your brain and spinal cord. A CSF leak is not the most common cause of a postural headache, but it can be an emergency.
Sometimes, this fluid leaks through a hole in your meninges or skull, usually due to:
CSF leaks can also happen spontaneously without a known cause.
Other conditions can also cause positional headaches, including:
- Dehydration. Low fluid volume in your body can cause a drop in your blood pressure when you stand up.
- Severe anemia or blood loss. When your blood volume is low, blood flow to the brain is diminished, and the headaches are worse when you stand up.
- Postural orthostatic tachycardia syndrome. Often referred to as POTS, this condition involves a rapid heartbeat and changes in blood pressure when you stand up.
Colloid cyst.This is a noncancerous brain tumor. If it grows large enough, it can interfere with or block the circulation of CSF.
- A brain tumor or metastasis. Any brain tumor can block CSF flow in the brain, resulting in a major change in CSF pressure when you stand.
If you have symptoms of a positional headache, it’s important to see your healthcare provider to rule out any serious conditions that need quick treatment, including a CSF leak.

During your appointment, your healthcare provider will ask about your symptoms. Make sure to tell them what seems to make the pain go away, such as standing up or lying down.
If they suspect you have a CSF leak or tumor, they may do an MRI scan of your head and spine. This will help them see your meninges and identify any areas of unusual pressure, which could indicate a leak.
Your healthcare provider might also perform a tilt table test to rule out POTS.
This involves lying down on a table. You’ll be strapped to the table, which will suddenly change positions after about 15 minutes. The table will remain upright for about 45 minutes while your healthcare provider monitors your blood pressure and heart beat.
CSF leak treatment
If you have a CSF leak, the first step of treatment could involve several days of bed rest and drinking plenty of fluids.
During this period, you’ll need to avoid heavy lifting and try to limit:
- other similar actions
Reducing any kind of pressure or straining can help the hole causing the leak to close up on its own. Your healthcare provider might even recommend taking stool softeners to avoid extra straining when going to the bathroom.
If rest doesn’t seem to help, they may recommend an
This involves injecting some of your own blood into your lower spine. This can plug a CSF leak in your spine. This usually cures a CSF leak within a few days, but you might need to have this done more than once if your symptoms don’t improve after the first blood patch.
In other cases, your healthcare provider might be able to surgically repair a very large hole, especially if they know its exact location.
If you have a tumor or colloidal cyst, your healthcare provider might remove it with surgery. However, if it’s small, they may decide to just keep an eye on it and prescribe medication to help manage your symptoms in the meantime.
There’s no cure for POTS. However, there are several things you can do to maintain a consistent blood pressure and reduce your symptoms, such as:
Persistent and severe positional headaches may be a sign of a CSF leakage, though other things can cause them.
If you have a CSF leak, there are several treatment options, especially if you catch it early. Regardless of the treatment your healthcare provider recommends, expect to spend a few weeks resting.
While there’s no cure for POTS, available home treatments and medication can help you to manage your symptoms. Be sure to make an appointment with your healthcare provider as soon as possible if you have symptoms of a positional headache.
