Hello @lenamarissa, I would like to add my welcome to Connect along with @windyshores and others. I know it must be really frustrating having constant dizziness and still no answers after seeing many doctors, ENTs, cardiologists, neurologists and physical therapists. My daughter had similar symptoms but it wasn't constant. After a few years of fainting episodes we found out she had Long QT Syndrome which was diagnosed by a Mayo cardiologist. I'm sure you have probably done a lot of searching but if not these Mayo Clinic references have some information that may be helpful:

-- Dizziness - Symptoms & causes: https://www.mayoclinic.org/diseases-conditions/dizziness/symptoms-causes/syc-20371787
-- Symptom Checker - Dizziness in Adults: https://www.mayoclinic.org/symptom-checker/dizziness-in-adults-adult/related-factors/itt-20009075

Have you thought about seeking help at a teaching hospital or major health facility like Mayo Clinic?
