If the bumps on the skin are long white streaks with a strong odor, they are usually sebaceous cysts. These cysts have been previously infected and the sebaceous secretions stored inside have decayed into a white tofu-like residue. If there is no visible inflammation on the surface of the skin, such as redness, swelling or pain, then regular skin cleansing and disinfection with a skin disinfectant is recommended. However, if there is significant redness, swelling, pain, etc., then surgery is recommended to remove the entire sebaceous cyst.
