This study looked at two types of nerve block injections used to treat people with cervicogenic headache (CEH) and occipital neuralgia (ON)-two painful conditions that often cause pain at the back of the head and neck. The injections target nerves in the upper neck that may be causing the pain.
The researchers compared:
One nerve injection (greater occipital nerve block, or GONB), versus
Two nerve injections (GONB plus lesser occipital nerve block, or LONB).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| GONB Alone | Experimental | Patients received a single injection of 1 mL of 2% lidocaine at the greater occipital nerve using a landmark-guided technique. |
|
| GONB + LONB (Dual Block) | Experimental | Patients receive two injections of 1 mL of 2% lidocaine each at the greater and lesser occipital nerves using a landmark-guided technique. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Greater Occipital Nerve Block (GONB) | Procedure | A landmark-guided injection of 1 mL of 2% lidocaine administered at the anatomical location of the greater occipital nerve (GON) to treat cervicogenic headache and occipital neuralgia. Performed without corticosteroids or imaging guidance. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in pain intensity measured by the Visual Analog Scale (VAS) | ain intensity was assessed using a 10-point Visual Analog Scale (VAS), with 0 indicating no pain and 10 indicating the worst pain imaginable. VAS scores were recorded at baseline and follow-up visits. | Baseline, 24 hours, 3 weeks, and 3 months post-intervention |

| Combined Greater and Lesser Occipital Nerve Block (GONB + LONB) | Procedure | Two landmark-guided injections of 1 mL of 2% lidocaine each at the anatomical locations of the greater and lesser occipital nerves. Performed without corticosteroids or imaging, targeting broader nerve involvement in cervicogenic headache and occipital neuralgia. |
