My husband bruised his rt shin on exercise equip and has a big bruise 2 weeks ago. He then developed a 3 in blister on top the bruised skin. He covered it so he wouldn t bump it but it began leaking and there was some swelling in the leg. He saw his doctor who put a gauze bandage on it with a wrapped the lower leg and prescribed 10 day atbx and elevate the leg as much as possible. It was draining through the layers of bandages. He returned to the Dr and he cleaned the wound and wrapped it again with a uniboot (spelling). It is draining through again. I don t see how the wound with no skin on it will heal wrapped with no air on it. I m thinking he should see a wound specialist as it is going on 3 weeks.
