The first step is to determine the nature of the meatus; if it is a tumor, the lipoma in the intestinal lumen needs to be removed, which is a benign tumor. If there are no symptoms, and the size is small and does not affect the appearance, it can be left untreated for the time being. If the lipoma is getting bigger, it can be surgically removed. There is also the possibility of a malignant tumor of the parotid gland, where the lump usually grows rapidly and with discomfort, and must be operated on as soon as possible. If it is oral mucous membrane polyp, you can do anti-inflammatory treatment, and at the same time, take heat-removing and detoxifying drugs. If it is a flesh lump on the inside of the cheek, it is considered to be oral ulcers, you can use oral ulcer paste, ice boron powder for external treatment. The appearance of meat bumps, do not worry too much, usually eat more vegetables, fruits, if the symptoms after the anti-inflammatory still did not relieve, it is best to go to the regular hospital in time for examination.
