What happens when cupping pulls out blisters?

Cupping is a common problem encountered during cupping. It is normally caused by excessive moisture in the patient's body. This type of blister is normally multiple small blisters. No special treatment is required after the blister appears. It is only necessary to prevent friction with the blister when bathing or taking off clothes, causing the blister to rupture. However, some water cannons are caused by improper operation. If the negative pressure is too large or the tank is left for too long, it may show relatively large blisters. This kind of blisters must be treated. You can use sterile needles to puncture blisters, and use iodophor locally to disinfect to prevent local infection. We must not be too nervous.
