Hi, Hope you are fine now. I can understand your concern. I know it s very stressful when there are symptoms with no diagnosis. It is a common clinical problem that vertigo, most often, there will be no apparent diagnosis. Usually we will treat according to the symptoms and signs. And most often than not the patient will be having the symptoms even after proper medication. The BPPV is diagnosed with certain clinical criteria involving the positioning and turning of the head in certain angle to provoke the vertigo along with some jerking of the eye ball which only the doctor will notice. In your case, I am taking that the diagnosis os based on that criteria. The symptoms you are telling can be due to a variety of diseases involving your eyes, heart, brain and muscle. So try to have a complete workup involving the ophthalmologist, Neurologist, Cardiologist and if possible with a Rheumatologist. It is good to know that you are fine clinically rather than living in stress that you have some disease. Try to have these consultations as early as possible. And Lyme disease can have neurological symptoms. So these encounter with these doctors can rule out that too. Hope i answered your query. Further queries, you are welcome to message me. Regards, Dr. Arveen A Sulfath
