Incidentally I just returned from Mumbai where there was an International Conference on Vertigo!
Vertigo is just a symptom where the patient has a subjective experience of imbalance! It could be due to different reasons and this is what requires all the diagnostic skills of the doctor to come to the right diagnosis.
Next Steps
Please meet a good ENT Specialist who is specially equipped to treat Balance disorders in Mumbai. Practo has the best listing. Use patient feedbacks to guide you.
