Blood blisters develop when blood collects between the upper layers of the skin. This forms a bump on the skin that resembles a bubble. Blister fluid might also be contained.
Friction and trauma on the skin are the common causes. Some diseases and medical conditions can also cause the blisters. In most cases, they heal on their own even without treatment.
Some blood blisters such as in the mouth can heal in days. Others like on the toes can take months to clear completely. Luckily, there are several options that can quicken the healing process.
How long does a blood blister take to heal?
On average, a blood blister takes 30 to 48 days to heal. This period can be shortened or lengthened depending on the measures being put in place.
Continued assault on blood blisters make them larger and encourage tearing. For this reason, the first thing that should be done is get rid of all sources of friction and pressure.
Infected blood blisters are harder to treat. Infections are mostly caused by bacteria. Viruses can also lead to infections, especially for blood blisters in the mouth.
Factors that determine
So, how long does a blood blister last? The following factors determine the recovery period of a blood blister:
- Cause – blood blisters caused by minor causes such as first-degree burns will clear in a week or two. The same can be said about blood blisters in the mouth due to accidental biting. If caused by medical conditions such as lack of platelets in the blood, they will keep reappearing even after healing. For blood blisters under the fingernail or toenail, they can take up to three months to clear.
- Size – bigger blood blisters take longer to heal. In fact, most of them break open at one point. This calls for more complicated treatment options.
- Damage to blood vessels – severely damaged blood vessels will leak more blood. They will also take longer to mend. With time, the trapped blood gets reabsorbed. Damaged vessels are likely not going to reabsorb the blood efficiently.
- Treatment – while there is no specific treatment for blood blisters, several things can be done to quicken the healing process. In absence of such measures, the blisters will take longer to heal.
- Location – blood blisters on feet are more likely to be constantly assaulted. They also are likely to have been formed by harsher means. For example, a blood blister under the toenail can be caused by trapping the toe under a blunt heavy object. Such a blister will take months to heal. In fact, it will cause the toenail to fall off.
- Type – most blood blisters are raised above the skin. They last longer compared to blood blister under skin.
Tips to quicken healing
Keep it protected
Dressing a blood blister with a bandage is very advisable. It keeps the blister from assault as well as from infections. When dressing with a bandage, make sure the middle part is raised a bit. This prevents from excess pressure on the blister.
Allow it to breathe
Circulating air keeps a blood blister dry. This encourages popping. When dressed in a bandage, you can remove it when going to bed and replace it in the morning. For a blood blister on the toe, consider wearing open shoes.
Treat it with ice
Cold compressing a blood blister with ice reduces inflammation and pain. It is very effective when started immediately after the blister has formed. To cold compress, wrap some ice cubes in a plastic bag and a small towel. Hold the bag on the blister for about 10 minutes. You can use a cold spoon for blood blisters in the mouth.
Painkillers may help you retreat from considering having the blister popped. Antibiotics are necessary when the blister has been popped or has broken open on its own. Appropriate treatment should be sought if the blisters are caused by certain medical conditions. When a blood blister keeps coming back, it is often a symptom of a disease.
Try home remedies
With an appropriate home remedy, recovery period from a blood blister can be reduced by half. A number of home remedies to use against blood blisters have been discussed below.
How long does a blood blister last in mouth?
It is unlikely that a blood blister will be caused by something serious. For this reason, blood blisters in the mouth have a shorter recovery period.
For example, a blood blister caused by accidental biting may take less than a week to heal. If caused by hot foods and drinks, it may take about 2 weeks to heal.
Open blood blisters in the mouth are very prone to infections. They should be protected from popping. If they end up tearing on their own, consider antibiotic mouthwashes.
How long does a blood blister last on fingers and feet?
Hands, fingers, toes and feet are very prone to blood blisters. It is in these locations that blood blisters take the longest to heal.
A blood blister on the sole of the foot can, for example, take up to 10 weeks to heal. This is due to constant friction sustained on the feet.
The most important thing is to ensure that such blood blisters have been protected. On feet, a doughnut-shaped moleskin pad can be used as a cushion when walking. Since blood blisters worsen under moist and wet conditions, cotton socks can help. Right-sized or open shoes will keep from the occurrence of repeated friction on the blisters.
Wearing gloves on blistered hands is advisable when doing manual activities. Since the gloves will encourage sweating, they should be removed when not required. Gloves can also help protect from blood blister on finger due to frostbite in cold seasons.
How long does a blood blister last after popping?
How long does a blood blister last after it has been popped or has popped on its own?
After popping on its own, a blister will take about half the period it has existed to heal. Popping on its own is usually a sign of healing.
If manually popped, small blisters will take about a week or two to heal. For larger blisters, up to three weeks will be required.
You are not advised to pop small blisters. They heal faster when left alone. Larger blisters have a tendency of tearing on their own in the long run. They can therefore be popped in advance. Just ensure that proper measures to keep from infections have been undertaken.
How long does a blood blister last with home remedies?
Aloe Vera gel applied on a blood blister quickens healing. It also keeps from bacterial infections.
Turmeric powder or sandalwood powder made into a paste with honey and rose water keeps the blister dry and not inflamed.
Witch hazel’s antiseptic properties encourage recovery and also ease pain.
Tea tree oil diluted with water kills of microbial infections. Green tea drinks can also help keep from inflammations.
Garlic juice applied directly to the blisters will keep from infection. It also eases pain.
As to how long it takes blood blisters to heal, most of it will be determined by measures being put in place to encourage the healing process.
