When you get a scratch or a cut, you open blood vessels and that causes bleeding. While bleeding helps to clean the cut, your body stops bleeding eventually by producing platelets that clump together or coagulate at the spot of the wound. These platelets dry and clot to form a scab. The skin below the scab begins to heal with the help of white blood cells.When the skin is healed, the scab will fall off. This usually happens within a week or two. Although your scab may be itchy because of the healing process beneath it, you should not scratch it. If you pick away your scab you interrupt the healing process and could develop a scar.

How do scratches and cuts heal?

What is an avulsion?
American Red Cross answeredAn avulsion is a serious soft-tissue injury. It happens when a portion of the skin, and sometimes other soft tissue, is partially or completely torn away.
This type of injury often damages deeper tissues, causing significant bleeding. Sometimes a violent force may completely tear away a body part, including bone, such as a finger. This is known as an amputation.
With amputations, sometimes bleeding is easier to control because the tissues close around the vessels at the injury site. If there is a violent tearing, twisting or crushing of the extremity, the bleeding may be hard to control.
What is osteitis pubis?
Osteitis pubis is a condition that involves the gradual widening of the pubic symphysis. The pubic symphysis is the location where the pelvis connects in the front. Normally the condition occurs over time during participation in long-term activities such as running and soccer. The presence of a leg length discrepancy could increase the likelihood for a person to develop this condition.
