Have You Had a Severe Headache After a Spinal Tap? Learn Why It Happens and How to Find Relief

Have you ever experienced a severe headache after having a medical procedure involving your lower back? Perhaps the pain gets much worse when you sit or stand up, but feels better the moment you lie down flat. If this sounds familiar, you might be dealing with what doctors call a spinal headache.

While having intense head pain can feel scary and overwhelming, understanding what is happening inside your body can help ease your worry. This complete guide will walk you through everything you need to know about spinal headaches, why they happen, and how you and your doctor can treat them effectively.

What Is a Spinal Headache?

Simply put, a spinal headache is a very painful type of headache caused by a drop in the fluid surrounding your brain and spinal cord. This clear liquid is known as cerebrospinal fluid, or CSF for short. Think of your brain and spinal cord as delicate organs that float safely inside a fluid-filled cushion.

This protective fluid gives your brain important nutrients and acts like a shock absorber against sudden movements. If something causes this fluid to decrease or leak out, your brain loses its natural support system. Without that fluid cushion, your brain shifts downward slightly when you stand up, which pulls on sensitive nerves and blood tissues.

Doctors also use other medical names for this condition, including:

• Post-dural puncture headache.
• Epidural headache.
• Low-pressure headache.

Why Do Spinal Headaches Happen?

The primary cause of a spinal headache is a medical procedure where a doctor inserts a tiny needle into your lower back. This process is medically known as a lumbar puncture, often referred to as a spinal tap.

Lumbar Puncture Is the Main Reason.

Doctors perform lumbar punctures for several reasons, such as collecting a fluid sample to diagnose infections or delivering numbing medicine. You might remember receiving an epidural during childbirth to help manage labor pain. These procedures involve placing a needle into the spinal canal.

During this process, the doctor inserts a fine needle through the thin membrane covering your spinal cord to inject medicine or collect fluid. Sometimes, a tiny microscopic hole remains in this membrane after the needle is removed, allowing a small amount of cerebrospinal fluid to leak out.

When this fluid leaks, the pressure around your brain drops greatly. Doctors call this condition intracranial hypotension. Because the fluid cushion decreases, your brain sags slightly and pulls on nearby nerves, causing intense head pain.

Medical research shows that spinal headaches occur in roughly 10 percent to 40 percent of people who undergo a lumbar puncture, depending on the needle size and type used.

Are There Other Causes?

Yes. This back procedures are the most common cause, rare events can also cause fluid leaks leading to a spinal headache:

• The rupture of a fluid-filled cyst near your spinal cord.
• A tear in the protective membranes covering your spinal cord.
• Severe trauma to your head or face, such as a fractured skull.

What Are the Symptoms of a Spinal Headache?

If you develop a headache after a spinal tap, the pain usually starts within two to three days. However, in some rare cases, symptoms can appear weeks later.

The primary signs and symptoms include:

• A severe, throbbing pain usually felt at the front or back of your head.
• Pain that gets worse when you sit or stand up, but improves when you lie flat. This is the hallmark feature of a spinal headache.
• Pain that increases when you cough, sneeze, or strain during bowel movements.
• Feeling sick to your stomach or vomiting.
• Neck pain or muscle stiffness.
• Feeling dizzy or lightheaded.
• Changes in your vision and extreme sensitivity to bright light, known as photophobia.

also, some people may experience rarer signs:

• Ringing or buzzing sounds in your ears, known as tinnitus.
• Sudden hearing loss or muffled hearing.
• Numbness or tingling sensations in your arms, known as radiculopathy symptoms.

How Long Do These Symptoms Last?

Most spinal headaches last anywhere from a few hours to a few days. However, some people experience persistent pain for longer periods. If your headache lasts longer than 24 hours, you should contact a doctor right away.

Who Is Most Likely to Get a Spinal Headache?

Certain people face a higher risk of developing a spinal headache after a lower back procedure. Risk factors include:

• Being dehydrated and not drinking enough water.
• Having underlying systemic health conditions, high blood pressure, or a history of frequent headaches.
• Having a low body mass index or low body weight.
• The specific type and size of the needle used during the back procedure, as larger cutting needles carry a higher risk.

Young women between the ages of 20 and 40 who receive an epidural during childbirth are among the most common groups to experience spinal headaches.

How Do Doctors Diagnose a Spinal Headache?

A doctor diagnoses a spinal headache by reviewing your medical history, recent procedures, and specific symptoms. If you had a lumbar puncture or epidural within the last 14 days, the diagnosis is usually clear, and you may not need extra tests.

However, if you have not had a recent back procedure, your doctor may order an MRI scan to check your brain and spine for fluid leaks.

What Treatments Are Available?

Medical treatments for a spinal headache focus on restoring normal fluid pressure and relieving pain. Doctors typically recommend a combination of simple home care and medical procedures.

Things You Can Do at Home.

• Lie flat on a comfortable surface. Since standing and sitting make the pain worse, resting flat provides natural relief.
• Drink plenty of fluids and water. eating caffeine, such as coffee or tea, can also help narrow blood vessels and ease pain.
• Use safe, over-the-counter pain relievers recommended by your pharmacist or doctor.

Treatments Provided by Your Doctor.

If home remedies do not relieve your pain after a few days, your doctor may suggest an epidural blood patch. During this procedure, a doctor draws a small amount of your own blood and injects it into your lower back near the leakage site. The blood forms a natural clot that quickly seals the tiny hole. Most people experience fast, dramatic relief after this procedure.

In very rare cases where conservative care and blood patches do not work, surgery may be necessary to repair the leak.

Can You Prevent a Spinal Headache?

You cannot completely control whether a spinal headache happens after a necessary medical procedure. However, medical teams take precautions by using very small, non-cutting needles during lumbar punctures to minimize your risk.

What Is the Outlook?

You do not need to panic if you develop a spinal headache. Most cases, about 85 percent, resolve completely on their own without any invasive treatment. For those who need an epidural blood patch, 60 percent to 70 percent of patients find total relief within 24 hours.

Rare, Serious Complications.

Although extremely uncommon, untreated and severe spinal headaches can rarely lead to serious complications:

• Cerebral venous sinus thrombosis, which is blood clotting in the brain veins.
• Subdural hematoma, or bleeding and fluid collection around the brain.
• Seizures or sudden convulsions.
• Hypopituitarism, where your pituitary gland produces fewer hormones.
• Syringomyelia, which involves fluid-filled cavities forming inside the spinal cord.
• Brain herniation from severe pressure shifts.
• Coma and, in extreme rare instances, death.

These severe risks are very rare and are listed to highlight why persistent, severe head pain should always be evaluated by a doctor.
