Can vertigo be successfully treated without undergoing any diagnostic tests?

Dr Ethan has provided a good summary on the possible causes of vertigo. Vertigo is a type of giddiness whereby a patient feels that the room is spinning or he/she is spinning. If this is what you experience, then you should see an ENT Specialist first. Most vertigo are due to peripheral causes (meaning there is a problem with the balancing system of the ear). Central causes of vertigo (due to a problem in the brain) are fortunately much rarer.

Vertigo refers to the feeling of having a dizzy sensation. In TCM, it is categorized as "眩晕“(xuan yun). Patients often feel dizzy and get better when they close their eyes or when they rest. In severe cases, they may feel that their world is spinning, causing them to lose balance, feel nauseous and/or vomiting. In TCM point of view, dizziness is often related to the phlegm and dampness accumulated in your body. The phlegm and dampness cause your qi and blood in the body not being able to flow smoothly to your head, thus causing dizziness.
