Wounds generally grow firm in about 7 to 14 days, i.e. healing. The speed of healing depends on the location of the wound, the recovery of the wound and the individual’s constitution. If the wound is not infected as well as suppurating, the healing time generally varies greatly depending on the location. For example, wounds located on the head and face generally heal in 4 to 5 days due to a better blood supply, while wounds on the chest and abdomen take about a week to fully recover. For wounds on the back or buttocks, the healing time may be longer due to thicker skin and usually takes about 10 days to heal. In addition, wounds located in joints also take relatively longer to heal due to reasons such as flexion, extension and tension of the joints, and usually take about 2 weeks to fully recover. In the process of wound recovery, you should rest more, do not do strenuous exercise, to avoid the wound again tear, life should pay attention to the diet of light, do not eat spicy and stimulating food, to avoid affecting the healing of the wound.
