What are the means by which blood blisters heal?

Natural Process: With injury to our skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. The swelling occurs under skin layers and causes them to bulge creating a protective fluid cushion we call a blister. As the area heals, the fluid will be resorbed or when no longer needed, the blister opens and the fluid drains. This should take about a week. Cover and protect. ...Read more

I bit my lip a couple of months ago, and it turned into a blood blister. It would heal, then get worse. It went away completely but keeps coming back.

I bit my lip a couple of months ago, and it turned into a blood blister. It would heal, then get worse. It went away completely but keeps coming back.

Could be worrisome: You don't list your age, but skin cancers are pretty common on lips. If you are not continuing to injure them, by for example, habitually chewing on them, you need to have a doctor, dermatologist, or even dentist check this. ...Read more

Can you tell me, how are blood blisters suppose to heal?

Same as regular ones: Blood blisters are no different from regular blisters aside from filling w/blood rather than clear liquid. Best to keep blister intact. In other words, don't rupture it or poke it or drain it, whether blood or not. As long as blister is intact, contents are sterile. So just cover it up & protect it from trauma & injury. If fills w/pus or turns red w/pain, then go see your Family Doc for evaluation ...Read more

Blood blister: You need to keep pressure off the area. Use moleskin and cut a circle in it to put over the area. Then cut a second and third moleskin in the same way. Then the pressure will be on the moleskin and not on the blood blister. If this cdoes not relieve the symptoms, see your doctor. ...Read more

Did a lot of jumps and feet movement and i got a blood blister. Dancing again tomorrow. Any advice how to heal it overnight?

Better idea: Gotta disagree with doc. With injury skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. Swelling/bleeding occurs under skin layers and causes bulging creating a protective fluid cushion called blister. As it heals, fluid will be resorbed or when no longer needed, blister opens and it drains. This takes about a week. Keep it covered and protected/stay off it. ...Read more

I have a blood blister on the underside of my breast that has popped. How long will it take to heal and how can I tell if its infected?

I have a blood blister on the underside of my breast that has popped. How long will it take to heal and how can I tell if its infected?

Cause and effect: You need to identify why the blister developed and eliminate that problem. Then, the keys are to cover and protect the injured area with dressing changes every other day to allow healing. Remember that inflammation (red, hot, swollen and tender) are important parts of healing and do not necessarily mean infection. If the wound is healing, it cannot be infected. If it gets worse, see a doctor. ...Read more

What causes blood blister on roof of mouth and how long to heal?

What causes blood blister on roof of mouth and how long to heal?

Cause?: The most likely cause would be some irritation, perhaps from eating a hard or sharp piece of food, or accidental abrasion while brushing your teeth. However, without actually being able to see you clinically, we can't give you an accurate diagnosis. It should be gone in about one week. If it lasts more than two weeks, make sure you have it diagnosed by your dentist! ...Read more

Blood blister on lower leg that won't go away? I've popped it several times, and it bleeds, but never fully heals. Looks like a mole & no pain.

Blood blister on lower leg that won't go away? I've popped it several times, and it bleeds, but never fully heals. Looks like a mole & no pain.

Cherry Angioma: This is most likely an angioma, a dilated capillary/benign vascular tumor. They are not usually a health problem, more of an aesthetic issue. If it's small they are easily treated with a laser. Popping will just cause bleeding, but no improvement in the actual angioma itself. ...Read more

Yes on occasion one can become infected then it is time to open it, however the risk of infection in a dressed open wound is still higher than that of an intact blister. The blister will gradually resolve with time. ...Read more

How can you treat a blood blister?

How can  you treat a blood blister?

Leave or release: If the pressure is unbearable, clean it and a sterile needle with some alcohol and puncture it from the side to release the blood. Do not remove the roof as this will act as a natural dressing until the skin underneath heals and pushes this dead skin off. I recommend aquaphor and a bandage for 24 hrs after puncturing. And do not touch it if you are diabetic and it is on your foot - get checked. ...Read more
