Spinal Tap Headache: Causes, Relief & Recovery

Post‑Lumbar Puncture Headache: What You Need to Know

A spinal tap (lumbar puncture) involves inserting a needle into the subarachnoid space to collect cerebrospinal fluid (CSF). If CSF leaks from the puncture site, intracranial pressure drops, causing a characteristic positional headache.

Typical Features

• Worsens when sitting or standing; improves when lying flat.
• Often frontal or occipital, throbbing or dull.
• May be accompanied by nausea, neck stiffness, photophobia, or tinnitus.

Conservative Management

1. Bed rest – Lie flat in a quiet, dark room; most resolve in a few days to weeks.
2. Hydration – Drink 2–3 L/day; caffeinated beverages (coffee, tea) can help by constricting cerebral vessels and boosting CSF production.
3. Analgesia – Acetaminophen or ibuprofen for pain relief.
4. Caffeine supplements – 300–500 mg/day (equivalent to 3–4 cups of coffee) if tolerated.

Definitive Treatment: Epidural Blood Patch

If headache persists beyond 24–48 hours or is debilitating, an autologous epidural blood patch (15–20 mL of the patient’s own blood injected at the puncture site) seals the leak and provides rapid relief in >90% of cases.

When to Seek Care

Contact your provider if headache worsens, fever develops, or you experience neurological deficits (weakness, numbness, vision changes). A repeat imaging or second blood patch may be needed.
