I have experienced sudden hearing loss after a tooth extraction last October. Since that time, I have had vertigo and constant pressure and plugged ears. It comes and goes. Some days are better than others. I have been to an ENT, she said it was a viral assault , that is her only explanation. She did an MRI of my head - clear & normal. Why am I still experiencing this. Sometimes I am so dizzy I fall into the wall. Other times, not so. But I have constant ringing in my ear, and now my other ear is plugging up. I m always blowing air through my nose to hope for unplugging. Sometimes the ear unplugs, But the last 2 days have been miserable. I tried some ear drops and some under the tongue homeopathic, over counter meds, dramamine, and some methocarbimol. - nothing. works.
