Puncture, tear the skin … How best to treat a blister?

Puncture, tear the skin ... How best to treat a blister?

Finally the summer holidays! After spending the year locked away avoiding rain and Covid-19, we all want to enjoy the great outdoors. We take out sandals, hiking shoes and, for the bravest, running shoes to go back to running in the sun (but not in the sun, eh!). Except that between bad sneakers and deadly high heels, in the summer, our feet can get painful blisters.

A small sore that can do a lot of harm and that must be treated to prevent it from becoming infected. Should I puncture it or not? Tear the skin or not? 20 minutes gives you the steps to follow when you get a blister.

“It’s a mechanical reaction: the blister forms in the event of repeated friction between the skin and the shoe, explains Dr. Isabelle Rousseaux, a dermatologist. The rubbing causes inflammation and the outer layer of the epidermis peels off to form a blister that fills with fluid. “And if you can have blisters all year round, summer is all the more favorable. The heat makes you sweat more. then your feet swell, which increases the risk of getting one.

The good reflection

“The risk with blisters is that they get infected. Then, first, the area is cleaned with soap and water or with an antiseptic such as mercurochrome or eosin, prescribed by the dermatologist. Then, in the case of a large blister with a bubble full of liquid, you can take a needle, which you will sterilize with alcohol or by passing it over the flame of a lighter (letting it cool, of course!), To pierce it. After that, we put on a hydrocolloid dressing, special blister, which has a silicone gel consistency and which will relieve the pain by forming a small cushion on the bladder, protecting the wound and promoting healing.

For the next few days, “it’s about avoiding infection and ensuring proper healing, which can take about two weeks if you have a large blister,” says Dr. Rousseaux. The procedure consists of “disinfecting every day with an antiseptic. If the blister is large and raw, you can, during the first two or three days, wear a special blister dressing 24 hours a day to avoid nighttime friction. Otherwise, as soon as it starts to heal and be less painful, we let the skin breathe at night, he advises. So it is better to take a shower with the bandage on to protect the wound, then gently dry it, disinfect it and put on a new bandage “.

The false good idea

“The skin does not have to be torn: it acts as a natural dressing and promotes healing,” insists Dr Rousseaux. As for the grandmother’s remedy which consists in passing a thread through the eye of a needle, and then leaving it in the bulb after having pierced it, we forget. “Because it could cause an infection,” continues the dermatologist.

And if you have blisters and are already in your vacation spot, “it is best to avoid going barefoot in the sand when it is very cool. The risk: clinging to the raw, still painful wound, Dr. Rousseaux remembers. Another bad idea is to immerse yourself in sea or pool water, with the risk of infecting the wound. It is a precaution to be taken only at the beginning, ”he reassures him.

It happened to them

As a good pro of the resolutions we don’t keep, Julie had promised herself to get back into the sport. “I finally canceled my subscription to the room, where I hadn’t set foot for a year, the young woman confides. Three months ago, with the return of sunny days and the prospect of a summer vacation in a bathing suit, I wanted to go for a run. I put on my new sneakers and, after twenty-five minutes of not very comfortable walking, my face was red as a tomato and especially the hollow of the sole of my left foot was hit by a huge blister. When I got home, I washed my foot with soap and water, wiped it gently and punctured the bladder with a clean needle, then disinfected it with an antiseptic spray. But at night, with the rubbing of the perforated bladder against the sheets, I had a lot of pain. Suddenly, the next day I cut the loose skin. Clearly, it wasn’t a good idea. The skin was rough underneath, for three days I had a hard time walking! Fortunately, I was teleworking because I was in a lot of pain with every step. It took more than three weeks to heal properly! “

And Julie picks them up. “I must have blisters on my feet!” A few days ago these are low-heeled sandals that got the better of my little feet, in a few minutes I had two blisters, small but already sore with every step. In practice, “there are no blistered feet, but blistered shoes,” Dr. Rousseaux points out. Very often they are formed due to unsuitable shoes, new or too tight, and it passes very quickly ”. Like Julie, who didn’t hang around: “I rushed to the nearest supermarket and got some blister dressings, with a gel consistency, to ease the chafing. It is so effective that now I always keep one in my bag to be ready! “
