Blood blisters develop when blood and blister fluid collect between the layers that form the upper skin. This occurs when trauma is sustained on the affected area. The trauma causes injury to blood vessels, which then leak blood, forming a bubble. Common sources of trauma include friction, forced pinching, or crushing.
Often, blood blisters will heal on their own even without treatment. But they can at times be not only painful but also potential causes of infection.
Medical treatment is only necessary in cases of infection or large blood blisters. In most cases, home remedies and natural treatments can help manage the situation. This includes preventive measures to reduce the severity of discomfort.
What causes a blood blister, symptoms and pictures
What causes a blood blister? Common causes include pinching, friction and other related sources of trauma. Note that blood blisters usually develop even after the skin has not broken open and bled externally, forming a blood blister under the skin. However, the opposite can happen.
For example, activities that require a lot of walking or running may cause blood blisters on the toes, the soles of the feet or even on the upper side of the foot. Wearing shoes that are too small or not wearing socks will encourage this. Activities such as digging, shoveling and so on will, on the other hand, cause blood blisters on the hands.
Blood blisters are not very different from friction blisters. The main difference is in the fact that blood blisters contain blood, which makes them red in color. Friction blisters on the other hand are filled with a clear fluid.
Initially, a blood blister will appear red and very highly inflamed. With time, it will turn purple or dark. The presence of blood is caused by sudden pressure or repeated friction sustained on the affected areas.
The most common symptoms revolve around tight bubble-like bumps, red in color and often painful, forming on traumatized skin regions. They mostly occur on hands, feet, mouth and joints. Any part of the skin can be affected, however.
For self-diagnosis, pictures of blood blisters can help. You can compare them with pictures of friction blisters.
How to get rid of blood blisters on your body
The best removal options for blood blisters depend on how severe the blister is. Below is a quick guide on how to get rid of blood blisters:
Blood blisters worsen with continued pressure on the already affected areas. The first thing you want to do is get rid of the source of trauma. You can, for example, consider wearing open shoes, wearing cotton socks or replacing the handle of the tool you were using. At any cost, keep the blister from tearing open, especially just after it has formed. It can be very painful. Furthermore, open sores attract infections.
Leave the blister alone to heal
Skin cells are continually being shed and replaced with new ones. With time, the affected skin will undergo the same process, ending up with a naturally healed blood blister. This process can take about a month or even more, however. To shorten the period, make sure that the blister is exposed to air most of the time. It also should be kept as dry as possible, as well as free from friction or even pressure. The best approach is to apply a bandage. The bandage should be loosely fitted. It keeps out infections as well as eases the pressure exerted on the blister.
Drain the blister
In some cases, blood blisters are better drained than left to heal on their own. For example, a blood blister can keep getting bigger and showing signs of tearing up. It can in fact, tear slightly at the edges. In such cases, the best removing option is to drain it all together. This should be done very carefully. If you don’t have the right tools or antiseptics, consider having a doctor drain the blister. Patients diagnosed with immune compromising diseases and conditions such as cancer and HIV are not advised to self-drain a blood blister.
Keep from infection
Harmful germs are everywhere about us, on our bodies and in the surroundings. At the first chance, they will enter the body and cause infections. Open skin parts are conducive entry points for such germs. For this reason, always make sure to clean, disinfect and cover an opened blister. Always remember to replace and disinfect a bandage you are using to cover the blister.
Get medical help
The main reason you may need to get medical attention for a blood blister is if it shows signs of infection. It can also be that the blister is increasingly reducing your work efficiency or messing with your posture. Some blisters may occur on sensitive regions such as the mouth or near the eyes. Cases such as red blood blisters on the breast have been reported. In other cases, it can be that blood blisters keep appearing even after successful treatment or have developed in clusters. In such cases, getting medical attention for getting rid of blood blisters is the best option.

Protect it and let it heal
