Headache after concussion? nerve block study halted early
NCT ID NCT03007420
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether injecting numbing medication and steroids near nerves in the neck or back of the head could relieve post-traumatic headaches after a concussion or head injury. The trial planned to enroll 16 people aged 14 to 45, but was terminated early, so we don't have clear answers. The approach aims to ease pain when standard treatments like rest or medication haven't helped.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Occipital nerve block or cervical medial branch block using lidocaine and dexamethasone
- What this could lead to
- If successful, this approach could offer a new treatment option for post-traumatic headaches that don't respond to standard care.
- What could go wrong
- The trial was terminated early with only 16 participants, so results are very limited. It is unclear if the nerve blocks are effective or safe long-term.
