Cupping is a common treatment in Chinese medicine, which has the effect of invigorating blood and moving qi, dispelling wind and removing dampness. Blisters are called blisters in clinical practice. When dense blisters appear at the cupping location after cupping, the first consideration is the dampness removed by the cupping. However, it is also possible that the blisters may be caused by damage to the mucous membrane of the skin due to prolonged cupping, or that the skin may be burned due to improper cupping. If blisters appear, first stop cupping and avoid cupping again for a short period of time. It is also important to take care of the blister to avoid infection. For small blisters, avoid touching them to cause them to break, and wait for the skin to absorb on its own, keeping the area as clean as possible in the meantime. If the blisters are large, it is recommended to go to a clinic or hospital where the blisters can be punctured and drained under a sterile doctor’s care. After the blisters have dried, antibiotic creams such as mupirocin ointment and metronidazole cream should be used to prevent infection, and sterile gauze should be used to cover the bandages. During the recovery period, avoid getting water on the affected area to prevent infection. Abstain from spicy and stimulating foods, such as chili, onion, pepper, etc., and hairy substances, such as beef, mutton, goose, seafood, eggs, etc. Also pay attention to cupping in the future under the operation of a professional doctor and pay attention to keeping warm after cupping to avoid getting cold.
