This study compares the effectiveness of greater occipital nerve blockade and sphenopalatine ganglion blockade in reducing headache intensity, duration, frequency, and disability in patients with episodic migraine.
Migraine is a chronic neurological disorder characterized by recurrent headaches, affecting millions globally. Peripheral nerve blocks such as Greater Occipital Nerve (GON) and Sphenopalatine Ganglion (SPG) blockade have emerged as promising non-pharmacologic treatments.

Patients will receive greater occipital nerve blockade using 2 mL of 2% lidocaine at the medial one-third of the line between the occipital protuberance and mastoid process.
Patients will receive greater sphenopalatine ganglion blockade using 2 mL of 2% lidocaine using a transnasal approach with a cotton swab inserted along the superior middle turbinate to the posterior nasopharyngeal wall.

Degree of headache intensity
Reduction in headache intensity will be recorded using numeric rating scale (NRS). Each patient will be instructed about pain assessment with NRS score. NRS (0 represents "no pain" while 10 represents "the worst pain imaginable").
Time frame: 3 months post-procedure
Migraine disability assessment score
The migraine disability assessment scores are as follows: little or no disability, 5 to 10; moderate disability, 1 to 20; and severe disability, more than 20.
Time frame: 3 months post-procedure
Headache duration
Headache duration will be recorded.
Time frame: 3 months post-procedure
Headache frequency
Headache frequency will be recorded.
Time frame: 3 months post-procedure
