The need to puncture blisters from cupping should be determined on a case-by-case basis. Mild cases can be left untreated, while severe cases need to be punctured and disinfected. Cupping is used to remove dampness from the body and has health and therapeutic effects. However, during cupping, blisters may appear due to factors such as prolonged cupping or excessive temperature, and may be accompanied by bruising, local skin redness, and other symptoms. In addition, if the patient’s body is too damp, this may also occur during the cupping process. When the blisters are small, they can be left untreated and will be absorbed by the body within a certain period of time and will naturally subside. If a large blister occurs during cupping, it can be broken with a sterilized needle and disinfected with iodophor, then covered with a sterile dressing to avoid infection of the skin break. Re-cupping is not recommended when the blisters have not yet recovered. The length of cupping should be decided according to the patient’s age, condition, and physical condition, with a general retention time of 5-20 minutes.
