The dark color left on the skin after cupping indicates that it is windy, wet and silted. "Many people have this view. The depth of color is related to the length of cupping stay time and the strength of negative pressure, which does not necessarily mean that there is wind, humidity and mud. It is even more unfounded to judge whether it is cold and dampness, internal heat or deficiency heat by the color after cupping.
After cupping, the longer you leave the cupping, the better. Generally, once 10~ 15 minutes is appropriate. Strong people can spend a little longer, while old people, children and weak people have a little shorter time. Cupping times should not be too many, and the same part should not be pulled often. Cupping for a long time may blister the cup-shaped skin and may also cause skin infection.
Pulling out blisters is pulling out moisture "is a classic misunderstanding, in fact, the skin is scalded." "
Blisters appear after skin scald, which can be judged as "second degree burn" in medicine. Therefore, don't blindly pursue thermal effect when cupping, and the blisters appearing in cupping can't be regarded as normal. If the skin feels overheated and painful, you should stop cupping by yourself, apply cold compress with ice water, and apply burn medicine appropriately.
Some people are not suitable for cupping. Such as thrombocytopenia, lupus erythematosus and severe skin diseases. Otherwise, it is easy to cause bleeding, or ulcers, blisters, edema and other phenomena appear on the skin surface.
It should also be specially reminded that patients with chronic obstructive pulmonary disease, tuberculosis, lung abscess, bronchiectasis and other basic lung diseases are not suitable for cupping. Pulmonary inflammation is usually accompanied by alveolar injury or pulmonary fluid retention. If cupping is used, the pressure in the chest cavity will change sharply, which will lead to the rupture of pulmonary bullae on the surface of the lung, thus causing spontaneous pneumothorax.
Cupping is not a panacea. If cupping has no obvious effect several times, you should see a doctor to determine what causes the discomfort. Never ignore it, so as not to delay the illness.
