There are two types of bruises on the feet, one is a phenomenon that occurs occasionally but can subside quickly, and is usually caused by subcutaneous bleeding due to the rupture of skin capillaries. In the other case, the bruises are present for a long time and are getting heavier, in which case varicose veins of the lower limbs occur, causing changes in the color of the skin. In the first case, it is only necessary to observe the change of the condition, which is usually completely absorbed in 2-3 weeks. If the symptoms are more severe, the topical drug Xylitol can be used to promote the absorption of the local hematoma and reduce the pain. In the other case, the patient should be seen in the vascular surgery department as soon as possible and have an ultrasound examination of the veins of the lower extremities to determine the venous reflux in the lower extremities and treat the condition accordingly to prevent this condition from getting worse and causing skin ulcers.
