Hello Doctor, My friend gashed his shin on a sharp cement edge of a pool approximately 3 or 4 hours ago. The cut is approximately 2 inches long. Right after the inicident, we rinsed it a bit with water and dressed it with gauze and applied some neosporin . We just took the bandage off and it needed a bit of oxygen and he had been walking, and running a bit, on it. It hasn t yet clotted, but it s not bleeding anymore. What should we do? Thank you, Elaine
