Hikers, runners or, simply, tourists eager to walk, share a common terror: the appearance of blisters on the feet. A simple injury with a good prognosis but that by itself can ruin a day in the mountains, a good time in a race or a day of sightseeing.
Actually, a blister is a defense mechanism that we have to protect ourselves against an attack. In this case, the aggression would be a repetitive friction or pressure, either between the skin and an external element (sock or footwear) or between itself (between the toes). The most superficial layers of the skin shed a liquid, generally transparent, although if the injury is more intense, bloody, so that it forms a “cushion” to cushion the area and prevent the slightly deeper layers from being affected and the injury was more serious.
It goes without saying that this accumulation of liquid, while protecting, is very annoying and is what really hurts us when we continue walking.
How to prevent a rash blister
We already know that blisters are caused by excessive friction, usually from shoes or socks. Whenever we release footwear, there is the possibility that, until it adapts correctly to our foot, it produces overpressure and friction in certain areas: toes, heel, ankle … We must avoid, as far as possible, the release of footwear to make some effort such as hiking or running. Even for tourism, it is recommended to wear footwear that we have already used previously to avoid displeasure. We must pay attention to socks and use them made of cotton or natural fibers. The ideal: that they breathe and adapt to the foot without it slipping inside. Likewise, previously moisturizing the feet with creams dedicated to this effect, can alleviate the problem.
How to treat a gallbladder blister
As a general rule, blisters should not be exploded. The accumulated fluid inside is sterile and keeps the lesion free from infection. However, as we have said before, it is precisely this accumulation of liquid that is so annoying to us.
In case it is impossible for us to stop and rest, the liquid inside could be drained by piercing the skin of the blister (only pierce, never cut the skin). It is highly recommended that the piercing element (needle or piercing element) be clean and, as far as possible, treated with a disinfectant liquid. At this time, the skin would already be perforated and, therefore, we must treat the blister as a wound that could be infected. We must remove the liquid by pressing carefully with a sterile gauze and then wash with serum and antiseptic liquids (Povidone Iodine, chlorhexidine …) preventing infection. Healing creams are also a great alternative since they disinfect and hydrate the area, improving friction.

Gel dressings have become popular lately. These are a great ally in the treatment and prevention of blisters and should be a travel companion in our medicine cabinet. They can adhere to the blister, previously drained, preventing the external environment from damaging its healing and keeping the area hydrated. In addition, its padding reduces the pressure of the blister and provides some relief.
At the level of prevention, there are some solid lubricant sticks. They are applied when it is anticipated that an area of the foot could be exposed to overpressure. It works in such a way that the friction is not as intense and, generally, by itself it prevents the appearance of a blister.
