Help. waited all year for vaca. now big blister on heel. cannot walk without pain. what can i do fast?

Leave it alone: Blisters are the body's natural defense against injury. A blister forms when the skin is irritated by anything , medication etc. If the serum bubble stays intact, the underlying skin will heel all on its own. Whenever possible, allow the blister to be open to the air, which will speed healing time, and when you must wear shoes or cover it with a sock shoes and cover it with bandage.
