A lump below the earlobe that hurts when pressed may be related to boils, sebaceous cysts secondary infection, lymphadenitis, etc. 1. Boil: mostly due to localized purulent inflammation of the skin below the earlobe, usually caused by staphylococcal infection, localized protrusion, may have redness, swelling, heat and pain. There will be a localized bag that is painful when pressed. 2. Sebaceous cysts secondary infection: the sebaceous gland ducts in the skin under the earlobe are blocked, and the sebaceous glands can not be discharged and retained to form cysts, with localized long bags and pain when secondary infection occurs. 3. Lymphadenitis: mostly due to inflammatory lesions in the ear canal, auricle and periauricular area, the local lymph nodes below the earlobe are enlarged and inflamed, so there will be a long bag and pain when pressed. If the earlobe grows a bag when pressed pain, it is recommended to consult a doctor in time to identify the specific causes of the disease, under the guidance of the doctor for treatment.
