A collection of fluid that can be found inside the outer layer of the skin is called blisters.
They are usually due to sudden exposure to heat or pressure on the affected region.
But, if you see that the blister is filled with blood, then it is called as blood blister.
It occurs when the blood, lymph and other body fluids are trapped inside the outside layer of the skin.
When these blisters erupt, they usually release fluid that has the same color that you see inside the skin.
Blood blisters can be red, dark red or dark blue.
The human body protects itself from injury due to pressure or heat in a form of blister.
But, if blood vessel ruptures or gets damaged due to the trauma, it causes a pool of blood to form underneath the main surface of the skin, thus, it is called blood blisters.
It can also occur due to allergies, skin infection, irritation and scalding of the skin.
Blood blister often occurs on the mouth and on the lip because body parts that have high supply in blood are highly susceptible to it.
Sometimes, blood blisters appear on the feet.
This is due to wearing of ill-fitting shoes or standing or walking for a long period of time.
Treating of blood blisters varies.
Most of the time they just disappear on their own, thus, treatment is unnecessary.
However, in some cases when they are big and very visible, one can apply ice or a cold pack.
The effected part can also be elevated to minimize the swelling or soak it in Epsom salt.
It is important to cover and bandage the blister properly to avoid it from rupturing.
It is also discouraged to burst the blister by yourself for it can get infected easily.
Blisters disappear on their own so there is no need for any treatment.
Yet, if the blisters are big, you can go to the doctor so that he can use a clean and sterilized needle to burst the blister.
Also, if it ruptures on its own, it is advised to clean the wound immediately and apply antiseptic solution to prevent infection.
To keep the blisters from forming in the toe, wear shoes that fit properly and avoid wearing shoes that are too tight.
Wearing very tight footwear increases chances of friction between the foot and the shoe, thus, increasing the chances of blood blister formation.
When doing things that increases the chance of developing blood blister in the hand, wear protective material such as gloves.
If you usually have blood blisters due to allergic reaction, then stay away from allergens that can trigger it.
These are some information about blood blisters.
Keep in mind that they can be prevented, thus, by simply doing little preventive measures, you can keep yourself safe from the discomfort it can cause.
