Blood blisters are red fluid-filled bumps under the skin. When a mild injury is sustained, such as a pinch, blood is released from the blood vessels and forms a fluid-filled sac. The best way to prevent blood blisters is to lower the risk of knocking parts of your body against objects.
For instance, wear shoes or socks and keep your feet hydrated and dry, prevent irritations by not using harsh chemicals on your skin, and prevent infections by washing your hands frequently and not touching sores or cuts on other people's skin. If you already have a blood blister, though, stay with us at oneHOWTO and find out how to treat a blood blister safely.
As soon as a blood blister appears, apply cold to the area. A good method to treat a blood blister is to put ice in a towel and rest it on your blister. Don't leave it on for more than ten minutes. By applying the wrapped ice, you'll reduce blood flow. The blood vessels will contract, and the blister will become significantly smaller.
Repeat this process two or three times, but remember to take a break of around five to ten minutes between applications. You must do your best to avoid cutting off blood supply and prevent frostbite.
In addition to ice, using a cold gel pack can also be effective. These packs are designed to conform to the shape of your skin, providing targeted relief for the blister.
You can also reduce the size of the blood blister by elevating the affected limb above the level of your heart. This will encourage blood flow back to the heart and prevent the blood from pooling in the affected limb.
Moreover, while elevating, try gentle movements of the affected limb to further facilitate blood circulation. This can help in reducing swelling more effectively and may speed up the healing process.
Don't burst a blister. The skin forms a protective layer against infections. If you break this barrier, the risk of infection increases. Therefore, fight the urge to pick at your blister. The blood in the blister will be reabsorbed by the body and won't give you any more problems.
Simply keep the area clean and avoid applying pressure to the blister.
It's important to note that if the blister is in an area that experiences a lot of friction, consider using a protective pad or cushioning to minimize pressure and irritation.
If the blister bursts, disinfect the area immediately. If you can, use local antiseptic or liquid ointment. If you don't have access to these, wash the area thoroughly with soap and water, and let the blood drain.
Then, dry well and cover it with sterile gauze or a clean bandage. Never remove the skin that's left over from the blister, or cut it: the more skin, the more protection given to the affected area and the quicker the blister will heal.
In cases where the blister is in a location prone to dirt or bacteria, consider changing the bandage daily to maintain hygiene and prevent infection.
The skin will regenerate in a few days. Keep an eye out for signs of infection such as:
- Heat: You may notice that the area is significantly warmer than surrounding skin.
- Color: The blistered area may become intensely red.
- Growth: The blister may grow larger and become inflamed.
- Pain.
A combination of the above is indicative of an infection. If you are experiencing these symptoms, seek medical attention to be prescribed oral or topical antibiotics to treat the blood blister and get rid of the infection.
Additionally, if you observe any pus or unpleasant odor, these could be further signs of infection that require prompt medical evaluation.
