A very dizzy head from a cold is mainly caused by an inflammatory reaction in the upper respiratory tract. At this time, avoid getting cold, take appropriate bed rest and avoid strenuous exercise. You should eat a light diet, do not eat spicy and stimulating food, and drink warm fruit juice and warm glucose saline. If necessary, you can also take appropriate medication for symptomatic treatment, such as vitamin C silver warp tablets, aminophenanthramine capsules. In addition, for the treatment of cold pathogens, blood tests and, if necessary, respiratory secretions, such as nasal discharge and sputum, can be taken for pathogen culture and drug sensitivity tests to adjust the treatment plan. In case of viral infection, you can choose drugs such as ribavirin and oseltamivir, while bacterial infection can choose drugs such as amoxicillin, cefoperazone and levofloxacin.
