Has anyone had a SPG block? That is short for sphenopalatine ganglion block. They go up your nose and inject something that is suppose to help migraines and other ailments. I have chronic migraines and have been getting SPGs for about 8 months. The last two times I have had the procedure I have suffered some fairly severe nasal irritation with drainage and dizziness. I believe the blocks did help at first but now it doesn’t seem worth it due to the adverse effects. If anyone else has had this procedure and have or haven’t had these effects, please comment. Thanks.
