Blood blister – to pierce or not?

Blood blisters are not only quite annoying, but above all painful – but can we prick them so easily? Here you can find out whether or not you can puncture a blood blister and how you can prevent blood blisters.

Regardless of whether you were out and about in unsuitable shoes or did the gardening without gloves – blood blisters are usually not long in coming in such cases. They occur when a certain area of ​​the skin is subjected to excessive stress and intense friction. This detaches the upper layer of skin and creates a gap between the upper skin (epidermis) and the leather skin (dermis). This gap is filled with water – or with blood. And that hurts a lot!

Can you pierce a blood blister?

In most cases, the blood blister recedes on its own – but what should you do if it takes a little longer and the pain is simply unbearable? If the blood blister is very small, you can try to relieve the pressure with a blister plaster, e.g. B. from Compeed. It also helps to cool the blood blister a bit. It is possible to pierce the blister with a disinfected needle, but it is not recommended. It is better to see a doctor who takes care of the bladder. If the blister is opened improperly, pathogens and dirt can get into the open area of ​​the skin and thus cause an infection. In the worst case, it can even lead to blood poisoning.

How to open a blood blister

If you want to avoid visiting a doctor, you should open the bladder as follows:
  1. Thoroughly wash your hands and disinfect a needle.
  2. Prick the blood blister and allow the blood to drain completely from the wound and collect it with a sterile swab.
  3. Treat the wound with an alcohol-free antiseptic wound spray, e.g. B. from Hansaplast , clean and then protect with a plaster or bandage from possible infections.
  4. The healing time is about three to seven days.

Never cut off the top layer of skin! It also serves as protection.

Important: If redness or swelling occurs on the affected skin area, fever or a general feeling of illness, then a doctor must be consulted immediately.

Blood blister burst: what to do?

If the blood blister bursts on its own, you should clean it thoroughly, then disinfect it and cover it with a plaster or compress and bandage. During the healing process, the area should be cleaned again and again. Also, change the patch and bandage regularly. If new skin has formed again, you can use a wound healing cream with dexpanthenol, e.g. B. from Bepanthen , but no greasy ointments and creams apply. These prevent the wound from “breathing” and can lead to infection. The ingredients of the marigold are also said to help with wounds such as a burst blood blister, as they have a disinfecting effect and promote wound healing.

prevent blood blisters

A few simple preventive measures are enough to prevent painful blood blisters from forming in the first place. First and foremost, one should avoid excessive friction being applied to the skin. For example, if you work a lot in the garden, you should definitely do this with gloves . Appropriate footwear is essential for long walks or hikes. In addition, hands and feet should always be moisturized so that the skin becomes more elastic and does not tear as easily. Here you will find a hand cream with particularly good ratings >>

Blood blisters: Also possible in the mouth

Blood blisters can also appear in the mouth – both on the tongue and on the gums. They are usually caused by minor injuries while eating. Other causes include an allergic reaction, alcohol and tobacco use, and vitamin C deficiency. In most cases, the blood blisters in the mouth will heal on their own. Be sure not to squeeze them out as this can result in a secondary bacterial infection . Also, pay attention to proper oral hygiene. If the blood blister doesn’t heal on its own, you should see your dentist.
