The goal of this double-blinded, randomized placebo controlled clinical trial is to to see if using a numbing medicine (lidocaine) on certain areas inside the nose can help with headaches, neck pain, facial pain and pressure, and other symptoms. It also aims to understand the pathophysiology that causes these symptoms. The main questions it aims to answer are: 1. Is applying numbing medication directly to the sphenopalatine ganglion (SPG) area, while watching through the scope to make sure it's in the right place, a workable and effective way to treat migraine headaches immediately and 24 hours? 2. Is applying numbing medication directly to the sphenopalatine ganglion (SPG) area, while watching through the scope to make sure it's in the right place, a workable and effective way to improve patient-reported outcomes? The 2-month study requires: * One virtual visit (on the computer) * One visit to the office for placement of the numbing medicine under direct vision * Daily headache diary entries that take less than two minutes to complete
