How do you treat blood blisters?

Depends on size: Small blisters (1 inch) will normally heal on their own. Do not let anythng rub on it. You can use a doughnut shaped pad to pressure of it.Keep it clean and dry. If it breaks do not remove the skin flap unless it is dirty. You can apply an anti-biotic ointment and loose bandage.Change it daily and do not wear shoes that will rub on the area. See dr. For increased redness, drainage, fever.

Blisters: It does depend on the location and size and cause and pain or not, but usually benign neglect.

Protect it: An unpopped blister represents a closed sterile environment. Yes on occasion one can become infected then it is time to open it, however the risk of infection in a dressed open wound is still higher than that of an intact blister. The blister will gradually resolve with time.
