Some blisters after cupping can heal by themselves, some need to be treated, depending on the size of the blisters, the number of blisters and whether there is a feeling of swelling and pain. 1.

If the blisters appear after cupping are small in size and number, and there is no obvious feeling of swelling and pain, no special treatment can be done, because the skin has a certain self-healing ability. Sterilize the blisters daily and wait for them to absorb and heal on their own. 2. If the blisters after cupping are large in size and number, and there is local distension and pain, it is necessary to disinfect the blisters, use a sterile syringe to draw out the blister fluid, disinfect the blisters and bandage them with sterile gauze, pay attention to keep the blisters clean and dry, disinfect the blisters at regular intervals and change the gauze, and when the blisters crust and fall off, it will be healed. 3.
