I woke up in middle of night with severe ringing in both of my ears that is so loud it completely overwhelms me. it lasts only a minute but it builds to a point so loud it feels like my ears are being zapped. this is second time its happened?

Tinnitus: Tinnitus is a very uncomfortable condition. It is frequently traced to inner ear hair cell damage caused by exposure to loud sounds, whiplash, head injuries, too much ear wax, or medication side effects. It can worsen with age, dehydration, and specific diseases (Meniere's disease, high blood pressure) Treatment involves addressing the underlying cause. Talk to your Dr for exam, tests & treatment.
