What does bruising after cupping indicate?

    In general, bruising after cupping may be caused by excessive negative pressure inside the cup, prolonged cupping duration, fragile local capillaries, abnormal coagulation function, or allergic purpura. It can usually be managed through local heat application, reducing stimulation, and medication. If abnormalities occur, timely medical consultation is recommended. Detailed analysis is as follows:

    1. Excessive negative pressure inside the cup: When the negative pressure inside the cup is too high during cupping, it excessively pulls the local skin and subcutaneous tissue, causing rupture of capillaries and resulting in bruising. It is recommended to reduce the negative pressure appropriately during the next cupping session to avoid excessive suction. Bruising can fade naturally after appearing.

    2. Prolonged cupping duration: When the cupping duration exceeds the normal range, continuous negative pressure can worsen capillary damage, leading to bruising. The duration of cupping should be controlled, and after bruising appears, heat application can be used to promote local blood circulation and accelerate the fading of bruising.

    3. Fragile local capillaries: Some individuals have fragile capillary walls in certain areas, and even slight negative pressure during cupping can cause vessel rupture and bruising. This may often be accompanied by slower fading of bruising and possible recurrence. Treatment mainly involves taking medications such as vitamin C tablets, troxerutin tablets, and compound rutin tablets as directed by a physician to enhance vascular wall elasticity.

    4. Abnormal coagulation function: Deficiency or dysfunction of coagulation factors leads to reduced blood clotting ability, making bruising more likely and extensive after cupping. It is often accompanied by slow wound healing and gum bleeding. Patients can take medications such as tranexamic acid injection, ethamsylate injection, and vitamin K1 injection as directed by a physician.

    5. Allergic purpura: Allergic reactions of the body to certain substances cause inflammation of small blood vessels and increased vascular permeability, making bruising more likely after cupping. It is often accompanied by symptoms such as skin purpura, joint pain, abdominal pain, and hematuria, with the condition prone to recurrence. Treatment requires medications such as loratadine tablets, prednisone acetate tablets, and cyclophosphamide tablets as directed by a physician.

    In daily life, one should choose reputable institutions for cupping and avoid performing it independently. After cupping, attention should be paid to protecting the local skin and avoiding further impact or pressure. If bruising persists for more than two weeks without fading, or is accompanied by bleeding symptoms in other areas, prompt medical consultation and examination are advised.
