Study Arms:
- Greater Occipital Nerve (GON) Block with Lidocaine (Type: EXPERIMENTAL): Subjects randomized to this arm receive 2 mL injection of lidocaine 2% over the right and left greater occipital nerve at the baseline study visit.~All subjects then complete daily headache-related questions through a Headache Diary and other assessments for 28 days.
- Greater Occipital Nerve (GON) Block with Saline (Type: PLACEBO_COMPARATOR): Subjects randomized to this arm receive 2 mL injection of preservative-free normal saline over the right and left greater occipital nerve at the baseline study visit.~All subjects then complete daily headache-related questions through a Headache Diary and other assessments for 28 days.

Based on this trial design, predict the completion outcome and termination type (if applicable).
