Bleeding spots on the front of the calf with ulcers can be caused by varicose veins, narrowing of the arteries and skin infections on the front of the calf. 1. Varicose veins: In varicose veins, the return of blood to the veins of the calf is impaired, which can lead to localized venous blood stasis, increasing venous pressure and causing thinning of the walls of the venous blood vessels. When the venous blood leaks into the subcutaneous tissue, bleeding spots can be seen on the front of the calf. Inflammatory factors and metabolites contained in the venous blood can cause nutritional disorders in the skin, resulting in calf ulcers. 2. Arterial stenosis: If the patient’s calf artery is narrowed, it can cause the local vascular pulse pressure to increase, and the vascular permeability to increase, thus causing subcutaneous hemorrhage. It will also lead to insufficient blood supply to the front of the calf, and the surrounding tissues will not be fed by blood for a long time, and ulceration will occur, i.e., the formation of ulcer surface. 3. Skin infection on the front side of the calf: If the skin on the front side of the calf is infected by bacteria, viruses and other pathogenic microorganisms, leading to the rupture and bleeding of the capillaries distributed here, and the death of the skin cells, the bleeding spots on the front side of the calf with ulcers may appear. If the bleeding spots on the front of the calf are accompanied by ulcers, it is recommended to go to a regular hospital to find out the cause of the disease, and then actively cooperate with professional doctors for treatment.
