It is not usually recommended to puncture blood blisters, as puncturing them relieves pain but can lead to the development of infection. It is usually recommended that the surface be disinfected with iodophor and then bandaged. For those with significant localized pain, oral pain medication can be taken to relieve the pain. Patients with blood blisters on the bottom of the foot need to minimize walking to allow absorption of the blood within the blister. Blood blisters present in the mouth are absorbed more quickly and it is usually recommended to allow them to absorb on their own because there are more bacteria in the mouth and blood blisters are prone to infection and ulcers after lancing. For blood blisters on the hands, torso, legs, or burns, it is also usually not recommended to puncture them, and again, iodophor or alcohol can be used to disinfect them and then bandage them.
