In most cases, abrasions can heal in 1-2 weeks, which is closely related to the patient’s physical quality, the scope and depth of the injury, and whether there are underlying diseases, etc. For example, if the scope is small and the degree is not deep, the healing is fast. If the patient has a serious local infection and basic diseases such as diabetes, the wound will heal slowly, so after the bruise, you need to go to the hospital for treatment in time. You can consume vitamin-rich fruits such as apples, kiwi, bananas, etc., and foods rich in high quality protein such as fresh fish and fresh shrimp, etc., which can promote the healing of the wound as soon as possible. Try not to get wet and do not do too strenuous exercise, which can help the body to recover as soon as possible.
