Hey, new here. Looking to purchase an El Silverado Zapper in the hopes of it helping get rid of my middle ear infection/Eustachian tube dysfunction. Got it from a cold back in October, and it has been increasingly getting worse these past couple weeks. Have ringing in my ears, particularly my left ear. Ear drops and nasal spray don't appear to help. Neither do any medications. I really don't want to risk surgery. Is this a smart decision for me?
