Orthostatic Headache worsens when you stand up and subsides upon lying down. This is also known as Postural Headache as it changes in intensity upon changing the position. First suspect of an Orthostatic Headache is usually CSF leak that occurs after a Spinal tap or lumber puncture
Location of pain
Pain is usually felt at the back of head but if Orthostatic Headache has a secondary cause the pain may differ in location.
Duration of pain
The pain usually becomes debilitating when a person stands up but goes away slowly in a duration of 20 to 30 minutes upon lying down.
The symptoms usually depend upon the type of headache but most commonly observed symptoms in an Orthostatic Headache are
- Severe pain at the back of the head
- Vision problems
- Low blood pressure
- Blurred vision
Pain is usually aching, throbbing, pounding, stabbing, pressure-like, or pulsating depending upon the cause. This is most commonly associated with Low-pressure headache but other headache types may also show these signs.
- Orthostatic Headache is mainly due to low pressure exerted at the brain by Cerebrospinal fluid. This can be due to many reasons such as CSF leak, Hypotension Headache, Spontaneous Intracranial Hypotension (SIH), Spinal Headache, and others. As the CSF volume decreases, brain buoyancy decreases, and the brain along with other skull contents shifts downwards stretching the Dura along with it, causing a headache.
- Low blood pressure can also cause Hypotension Headache that aggravates upon standing up and relieves when the person lays down.
- A sinus or a cerebral lesion might also be the cause as it would get stimulated upon changing position.Other causes are:
- The first cause you doctor might want to rule out is CSF Leak, for that your history of any Lumber puncture or Spinal Tap might confirm the diagnosis.
- Other than that MRI Scans, CT Scans, and Contrasting Images might be suggested.
- Another test that is performed is a Tilt table test in which a person is strap-tied to a table that changes position at regular intervals of 15 minutes during this, changes in Blood pressure and Heartrate are monitored.
The treatment only depends upon the cause and severity of symptoms. Usually, lifestyle modifications are required for long term management of symptoms.
- IV fluids: for low blood pressure and Hypovolemia.
- Anti-Emetics: Metoclopramide for nausea.
- Epidural Blood Patch: to seal the CSF leak.
- Non-Opiate analgesics: for pain relief.
For Cysts, tumors, and abnormal growths a surgery might be required.
- Staying Hydrated.
- Doing regular exercise.
- Taking frequent meals.
- Increasing salt intake.
- Using compression stockings.
- Taking a well-balanced diet.
When to consult the doctor?
Consult your doctor as soon as warning signs appear such as Nausea, Vomiting, Vision problems, etc. Also, look for any changes in intensity and if your headache doesn’t go away after taking OTC analgesics.
It is most commonly caused by CSF Leak and Low blood pressure.
Improving diet, increasing salt and water intake can help
The duration only depends upon the cause. In-case of Hypotension, increasing the blood pressure back to normal can bring relief from the headache.
Subdural Hematoma, Meningitis, Trauma, Brain stroke or Tumor.
