Blister on the foot: you can do it yourself

Blisters on the feet are fluid-filled cavities under one of the layers of skin. The fluid presses on the underlying nerve endings - and that hurts. The deeper a blister is in the skin layer, the more painful it is and the slower it will heal. You don't have to sit by and hope that the blister on your foot will go away soon. Here are some tips you can use to treat your blisters yourself:

  • Smaller bubbles: Do not open - the intact skin over the bladder (bladder roof) offers the best protection against infections. To reduce friction, put a plaster or a piece of tape over the bladder - or a special blister plaster with so-called hydrocolloid technology. it can absorb and bind wound secretion if the bladder bursts.
  • Larger, tensioned bubbles: Prick only if the blisters are superficial. To do this, disinfect a clean needle with diluted alcohol, carefully prick the bladder, drain the liquid and let the skin dry a little. Then stick the plaster over it (disinfect the bladder beforehand if necessary).

In order to accelerate the healing process, you can take off a sticky plaster at night, then air will come in.

Never cut off the skin over a blister, otherwise it can become inflamed and more sensitive to pain.

Blister on the foot: Here's how to prevent it

Correctly taking care of an existing blister on the foot is one thing. It is even better not to let such a bubble develop in the first place. The following tips will help you prevent a blister on your foot:

  • Make sure you have well-fitting, padded shoes - regardless of whether they are street shoes or sports shoes.
  • Make sure that socks do not wrinkle in the shoe, as these can quickly cause a blister on the foot due to pressure and friction. Socks without exposed seams are best suited (e.g. special sports socks).
  • New shoes can quickly leave a blister on your foot. To prevent this, you can treat them with a deer tallow pen before wearing them for the first time - this reduces friction. It is also helpful to rub the inside of the shoes with soap or petroleum jelly.
  • As a precaution, you can cover up areas where blisters are particularly easy (balls of the feet, on the back of the heels, etc.) with a piece of tape or a plaster.
  • In hiking boots in particular, you should wear two pairs of thin socks on top of each other instead of one pair of thick socks. Then the socks rub against each other and not a sock against the skin - there is no blister on the foot.

Blister on the foot: causes and possible diseases

A blister on the foot is mechanical damage to the skin: it forms as a result of heat and rubbing under pressure after prolonged exposure to unsuitable footwear, for example on long walks or during sports. Because the friction shifts the upper layer against the deeper layer of skin until the two separate from each other. The resulting cavity fills with tissue fluid.

Blisters on the hands also form due to mechanical stress, for example when you work with a shovel in the garden for a long time.
