Due to individual variability, there is no quick way to remove bruises. There are many causes of bruising, such as trauma, allergic purpura and hemorrhagic fever, etc. It is necessary to choose the appropriate treatment for the cause, such as general treatment, medication and so on. 1. Trauma: If the bruise is caused by trauma, patients need to rest more and avoid strenuous exercise. During the period, you should follow the doctor’s instructions to use diclofenac diethylamide cream and other drugs to achieve the effect of activating blood circulation and removing blood stasis, reducing swelling and relieving pain. 2. Anaphylactic purpura: For the bruises caused by anaphylactic purpura, the first thing you need to do is to identify the allergens and avoid re-exposure. At the same time, follow the doctor’s instructions to take prednisone, dexamethasone and other glucocorticoid drugs, to play anti-inflammatory and regulate the immune system and other effects. 3. Hemorrhagic fever: Hemorrhagic fever is usually caused by hantavirus, which can also lead to skin bruising. After diagnosis, you should take ribavirin, oseltamivir and other antiviral drugs as prescribed by the doctor to promote the recovery of the disease. It is recommended that the patient go to a regular hospital, identify the cause of the disease, and cooperate with the doctor for standardized treatment.
