Most cases of itching and yellow discharge from the ears are mainly due to eczema of the external ear canal. This condition is caused by infection, allergy or low immunity of the body. In terms of treatment, the first thing to do is to keep the external ear canal clean and hygienic to avoid infection caused by forceful stimulation, and you can choose to apply topical dextrorol or hydrocortisone. If there is an infection, you can combine with Bactrim to apply it. If the symptoms are more serious, it can be combined with oral anti-allergy drugs, such as desloratadine tablets. If the disease recurs and recovers badly, you can also use drugs that regulate the body’s immunity, such as P-Transfer Factor Oral Solution or Skikon.
