Cupping blisters, if it is a small blisters generally do not need to be treated, the larger blisters using a syringe to draw out the liquid and then use iodine povidone sterilization. Cupping blisters is because the negative pressure in the can is too high, the skin can not withstand, resulting in a manifestation of skin damage. If the blisters are small, you can wait for the skin to absorb itself locally without treatment, and avoid touching the blisters to cause infection. If the blisters are large, the local skin should be sterilized with povidone-iodine and then the liquid in the blisters should be extracted with a sterile syringe to accelerate the healing of the skin, and then sterilized again to keep the local skin dry and clean to avoid infection. It is recommended that the cupping time is generally no more than 15 minutes, and when cupping, attention should be paid to avoid too much ignition material causing burns and blisters. If cupping out larger blisters should be to the regular medical institutions, by a professional physician to deal with.
