Treatment for Blood Blister

The treatment depends on the severity of the condition. It becomes necessary to seek medical attention if the blood blister is accompanied by the symptoms of an infection which includes, pain, redness and swelling beyond the area of the blister. If the blister is not accompanied by an infection, then mentioned below are some steps which you should follow while treating blood blisters at home.
  • The most common mistake that people end up doing is rupturing the blister and taking the top layer off! This is something which should NEVER be done as this may lead to a serious infection! Instead, you must focus on elevating the blood blister to prevent the flow of blood into the blister!
  • If the blister is painful, applying a cold pack on the blister would prove to be of help as it would help subside the pain. You can also use a moleskin to separate the blister from the rest of the skin.
  • If your blister is already punctured, then make sure that you keep the upper layer of the skin intact to prevent exposure of the raw and sore skin, and prevent further infection.
  • Application of an antibiotic on the blister would also prevent infection and would help heal the blister.
  • Washing your blister as often as possible with an antiseptic soap would also help you prevent further infection and keep the area clean.
  • Soaking the blister with Epsom salt also helps in reducing the swelling!
  • Do not apply tight bandage or cover the blister tightly as it may lead to friction during movement and worsen the condition. Let the blister be alone! Instead of a band-aid, go for a donut shaped moleskin pad which would cover the surroundings but leave the blister open.
Measures to Prevent Blood Blisters

Blood blisters can be prevented by taking certain simple and effective measures. These are mentioned as under.
  • If you are prone to getting blood blister on toes, or foot, then avoid wearing shoes that don't fit properly. This leads to unnecessary friction which causes blood blisters!

  • If you tend to have blood blister on fingers or hands, then it would be advisable to wear protective gloves whenever you perform an activity that involves constant friction.
  • Many people get blood blisters due to certain food allergies. These occur in the mouth. So, if you can think of the food that you are allergic to, avoid it completely!
It usually takes a few days for the blisters to heal completely. However, if the treatment options mentioned above don't seem to work for you, then you must consult your health care specialist as soon as possible, as these may be associated with certain other medical conditions too.
