Causes of Blood Blisters
Blood blister on foot and fingers is something which is very common in people involved with physical activities. But these may also occur in anyone, depending upon the causes. The causes of blood blisters are listed as under.
- Sudden trauma like pinching
- Burned or scalded area in the body
- Continuous friction due to rubbing
- Fungal skin infection
- Viral skin infection
- Ill fitted shoes
- Activities that involves friction like raking and shoveling, without wearing a proper cover.
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.
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!
- Moisture too, is one of the reason for the skin to develop these blisters. So keep your skin as clean as dry as possible.
- 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.
