Dizziness can be caused by a cold, but most dizziness is simply a feeling of dizziness and discomfort in the head, or a feeling of weakness, which is not strictly vertigo. Generally, when the symptoms of the cold gradually decrease, the dizziness will also gradually ease and disappear. In this case, no special treatment can be done, or when taking Chinese herbal medicines for deficiency colds, appropriate ingredients to benefit Qi, such as Radix et Rhizoma Ginseng and Radix Astragali can be added. The dizziness that occurs when you have a cold may also be accompanied by tinnitus and a feeling of spinning in the sky, which is caused by an associated infection that affects the vestibular nervous system. In this case, treatment may include oral diphenhydramine or intravenous betahistine hydrochloride to improve the local function of the vestibule. If the condition is accompanied by other conditions such as otoliths, corresponding treatment should also be done.
