A blood blister is a type of blister that develops when blood vessels are damaged near the surface of the skin. Blood blisters form after a pinching or bruising injury that does not actually break the skin. Since the blood cannot escape through an open wound, it collects beneath a bubble under the surface of the skin. Blood blisters are very similar to friction blisters. They usually do not require medical treatment and will heal on their own within three to seven days. However, if you want to get rid of a blood blister faster, you can try these steps:
- After washing your hands, gently wash the blood blister with mild soap and water.
- Apply an antibacterial cream or ointment onto the blood blister.
- Place a bandage or gauze over the blood blister to protect the area.
- Make sure to change your bandage at least once a day.
- Keep the area clean and dry.
- If you experience pain, you may want to apply an ice pack to the area. You can also try an over-the-counter pain reliever such as acetaminophen (Tylenol®) or ibuprofen (Advil®) .
It is important to avoid popping blood blisters, as the skin over the blood blister protects deeper layers of your skin from getting infected. If a blood blister breaks, it should be treated with antiseptic ointment to prevent infection. Blood blisters should be covered with a sterile, soft dressing and washed frequently to keep them clear of irritants.
