When your skin suddenly shows up or there are bumps filled with liquid that are black or purplish, you may panic. Well, this condition is known as blood blisters or blood blisters. Blisters are the appearance of a small sac filled with fluid that forms in the upper layer of damaged skin. These blisters can develop anywhere, but most often occur in the hands and feet.
What is blood blisters?
Blood blisters are a type of abrasion on the skin that develops into a small sac filled with blood from the blood vessels below the surface of the blister.
These blisters can appear after being pinched or experiencing bruises that do not damage the skin so much that the blood that appears from the inside cannot come out. The blood is still covered by a thin layer like bubbles on the surface of the skin.
The contents of the blisters can actually vary. For example blood or pus if infected. Well, the blood blisters will initially be red. Then when the blood starts to dry out and freezes, the color becomes purple black. The fluid that collects under the damaged skin tissue becomes a cushion for the underlying skin tissue.
What caused this blister?
There are many things that can trigger the appearance of blood blisters. Here are the various possibilities.
- Friction on the skin.
- Hot exposure, such as sunburn, burns, or after touching something very hot like a pan.
- Contact chemicals, for example contact with detergents.
- Medical conditions such as smallpox and impetigo.
- Medications taken can sometimes cause a reaction in the skin in the form of blood blisters.
In the case of blood-filled blisters, broken blood vessels near the skin surface are often caused by friction wounds on the skin. For example, your fingers have been pinched by the door.
Blood blisters can also be caused by a hard hit when kicking something or tripping. Continuous pressure from shoes or improper footwear can also trigger blisters on the skin.
How do you deal with blood blisters?
Actually, most of these problems can heal on their own after a week or two (it can be even faster). Fast or slow healing process naturally depends on how much blood is trapped.
Healing also depends on whether you reduce the emphasis on the part of the foot or hand that has blisters. Emphasis continues to make the old blood blister heal. For example, if you experience blisters on the toes, do not force the foot to continuously use closed shoes and press the blisters.
These blisters generally do not require special medical care. Because the new skin tissue under the blisters will grow by itself. Over time the skin tissue will absorb the liquid in the blisters until it dries and can peel off.
However, blisters that appear should be covered with sterile wound covers and blisters should be washed regularly to keep them clean. It is also important to keep blisters from breaking. Because if it breaks, it can cause infection and slow down the healing process. If blood clots rupture, keep the surrounding area clean and dry. You can also provide antiseptics to prevent infection.
This blood blemish often causes pain, especially if it breaks. To reduce pain, attach an ice pack to the blisters. Put the ice into a small towel to stick to the blisters, don't directly put ice on the skin. Leave for 10-30 minutes and repeat several times a day or every pain is felt.
