Input (English): [header] How to treat a foot blister [title] Cover your blister. [step] Foot blisters should be covered to reduce irritation and cut back on the risk of infection. Cover your blister with a soft dressing, like gauze or a loose bandage. <sep> (A) If the dressing becomes wet or stuffy, it is okay to use a bit of water or a bit of hand soap while covering your blister. [substeps] Keep the dressing soaked in either a small amount of water or by placing a clean cotton cloth or small drying bag on the blister. (B) If the blister is very sore, cut your dressing into a donut shape and place it around the blister to avoid putting pressure directly on it. [substeps] Your dressing should be changed each day. (C) [substeps] If you have the option, wrap a bandage around your blister. This will help reduce swelling and improve drainage. (D) Make sure you do not put your foot directly on the edge of the dressing as this could break the surface of the cotton. [substeps] If you have contact with soil during the night, then it's best to cover your blister when it gets cooler outside.
