Spinal Headache – Location, Causes and Treatment

Spinal Headache occur as a complication in people who undergo spinal anesthesia, epidural block, or lumbar puncture, thus are also known as Spinal Tap Headaches. This is common in around 50% of the people who undergo the procedure but the pain may vary in intensity, person to person.

Location of pain

The pain usually begins in the back of head or forehead and may spread in the whole head.

Duration of pain

The Spinal Headache may start within 1 to 5 days of the procedure, lasting for up to 24 hours. In most cases, the headache may go away within 24 hours without any sort of treatment. However, if a spinal tap headache does not go away in a day or more, it might need medical attention.

Symptoms

  • A dull, throbbing headache.
  • Dizziness and nausea.
  • Tinnitus.
  • Hearing loss.
  • Blurred or double vision (diplopia).
  • Neck stiffness.

Spinal Tap Headache worsens upon standing up or sitting down where as the patient may feel relief on lying down.

Causes

Spinal Headache occurs due to a decrease in pressure exerted by the spinal fluid on the brain and spinal cord when a spinal tap, epidural block, or lumbar puncture is performed.

Spinal tap involves withdrawing a small amount of cerebrospinal fluid from the spinal cord. However, during spinal anesthesia an anesthetic medication is injected in your spinal cord to block all the sensations from the lower part of your body. In both cases, a puncture hole is created which allows a small amount of spinal fluid to leak through it. This causes changes in pressure and thus a Spinal Headache.

Risk factors

According to a study:

  • Females are more prone to having Spinal Headache as compared to men.
  • A four fold increased incidence was seen in patients who have been suffering from tension headaches previously.
  • Patients who had repeated puncture attempts also are at greater risk of having Spinal Headaches.
  • People with a smaller body mass developed spinal headaches after the procedure.

Diagnosis

If you go to a physician with a complaint of a Spinal Headache, he might inquire about any recent procedures you must’ve had, like a lumbar puncture, spinal tap, or an epidural block. He might also suggest getting an MRI (Magnetic Resonance Imaging) done to rule out any other probable cause of headache.

Treatment

Treatment goes step by step and according to the symptoms.

  • Hydration: The first step involves keeping hydrated. In order to raise the pressure exerted by cerebrospinal fluid (CSF). However, if the patient is unable to consume a lot of fluid by the oral route, he is given intravenous fluids.
  • Caffeine: Your physician might suggest taking a strong coffee or any other drink high in caffeine.
  • Complete bed rest: Bed rest for 24 to 48 hours is mandatory.
  • Analgesics: Sometimes Analgesics are also prescribed to relieve the pain.

Epidural blood patch for Spinal Headache:

If your symptoms do not resolve in 48 hours, your physician might suggest getting an epidural blood patch. The process involves injecting a small amount of your own blood into your spinal cord over the puncture hole to seal it. The blood forms a clot and does not let more CSF to flow out. This restores the normal pressure of spinal fluid in a few hours.
