Cupping blisters need to be judged according to the size of the blisters, specific treatment measures. Smaller blisters do not require special treatment, while larger blisters need to be punctured, sterilized and bandaged in the hospital. In cupping physical therapy, if the temperature inside the can is too high or lasts too long, it is easy to cause skin burns and blisters. If the blisters are small, there is no need to puncture them, but they should be sterilized with iodine povidone and attention should be paid to keep the affected area dry and clean. However, if the blisters left behind by the fire cupping are large, they only need to be sterilized under the operation of the physician, and then the blisters should be pierced and the water discharged, and then the affected area should be bandaged with sterile gauze. It is important to prevent infection until the blister has healed completely. Avoid contact with sewage or contaminated objects. Blisters after cupping should be treated in a hospital.
