Deep vein infections should be treated with anti-infective therapy and prevention of thrombosis, and at the same time, good living and dietary habits should be maintained. 1. Deep vein infections should be promptly drawn blood for bacterial culture and drug sensitivity test, after clear diagnosis, symptomatic intravenous anti-inflammatory drugs (e.g. penicillin) should be injected. 2. Deep vein infections often have thrombosis, and embolus dislodgement can cause pulmonary embolism leading to serious consequences. Therefore, oral anticoagulant drugs, such as aspirin and low molecular weight heparin, should be taken on the basis of anti-infective treatment to prevent the formation of thrombus. 3. Prolonged standing, smoking and repeated infections will damage the venous lining, which will easily lead to aggravation of infection and thrombus formation, so it is necessary to develop good living habits. Pay attention to diet and avoid spicy and stimulating food. It should be noted that it is necessary to go to the hospital in time for examination and treatment under the guidance of the doctor.
