Certain lumps in ears can be treated with home remedies. This depends on the severity and the seriousness of the lumps. For example, sebaceous cysts can be treated with tea tree oil. Saturating a cotton swab with tea tree oil and holding it to the cyst for five minutes and washing it with oil-free soap dries up the fluids in the cyst. This minimizes swelling. Swollen lymph glands behind the ears can be treated by gargling with salt water or turmeric. Pain with mastoiditis can be treated by pouring a few drops of warm, Mullein oil in the infected ear. Garlic oil may also used for treating ear aches associated with infected ears.
