Patient case (clinical description): A 47-year-old woman comes to the clinic complaining of dizziness.  She also has occasional nausea and ringing in her right ear.  The patient also has difficulty hearing while holding her phone to the left ear, although hearing in her right ear is normal.  The dizziness improves spontaneously, and she feels fine between episodes.  Past medical history is notable for hypothyroidism and low vit D level, for which she is using Levothyroxine and Vit D pearl.  She does not use tobacco or drink alcohol. Physical examination shows sensorineural hearing loss in the left ear. She has only one-man sexual partner and menopaused 2 years ago.

Patient's own account: The other day, I had to go to the clinic due to severe dizziness. I'm 47 years old, and I've been suffering from nausea and ringing in my right ear. I also have difficulty hearing in my left ear while I hold my phone, even if my hearing in my right ear is normal. The dizziness just gets me all of a sudden but I don't have any symptoms in between 2 episodes. I suffer from hypothyroidism and low vitamin D levels. So I take Levothyrox and vitamin D pearl. I don't smoke or drink. They conducted a physical exam and said I had hearing loss in my left ear. My only partner is my husband, and I'm menopause for 2 years now.
