@minnmitzi I have had the same dizziness that can never be diagnosed. ENT sees nothing except my ears are constantly in tinnitus since a bout with a virus (Epstein Barr) years ago. Have constant clear mucous dripping (sometimes flooding) from nose and feel fullness in sinus on one side of nose. ENT still sees nothing. I suspect there is inflammation somewhere but no indication of infection on any blood tests. MRI of brain sees nothing. Had cataracts (starting in late 70's) and new lens. Left eye has never felt right or had real good vision but eye doctor finds nothing. Also have had stent and now a pacemaker for AFib. The heart meds, in my humble opinion, are part of the problem and in my case made the balance issues worse. No one knows. I have learned to not get up without having a handhold on something and to slow down while walking. The drs just do not seem to know how to treat this annoying symptom. The worst part is falling so do what you can to know where your feet are at all times. Wear good shoes, forget those heels. Keep trying as one day someone somewhere may find a real cure for the issues of tinnitus. I have gone from being able to climb on our rooftops like a mountain goat to barely navigating the flat floors, no steps, of our home. In the absence of a cure, we just have to adapt.
