How does a Blister Form – There are several reasons for bubbles to form on the feet. Most are formed by the friction of the feet with the floor, shoes or socks. With friction, the most superficial layer of the skin, the epidermis, takes off from the second layer, the dermis, becoming a collection of liquid between them, which comes from the blood vessels of the dermis. To prevent these blisters by friction, Vaseline can be applied in the place of friction between the shoes and the feet. There are commercially available products in the pharmacy based on Vaseline. Another option is to protect the area with tape.
In addition, cold or heat burns can also cause blisters, as well as ringworms, which are fungal infections. Ringworms can be diagnosed by the superficial scraping of skin flaking and analysis of this material under the microscope, or examination of fungus culture, made in a laboratory.
Another disease that presents with blisters on the feet is the dyshidrosis. It is a common disease, which courses with blisters on the hands and feet and a lot of itching. It can accompany a ringworm, or even be a reaction to used local or systemically substances or medicines. It especially hits the side face of the fingers, the palms and the plants of the feet. The itching can be so intense that the act of scratching breaks the bubbles that eliminate a transparent fluid. It occurs in outbreaks that end with skin flaking. It should be treated with creams or corticosteroids tablets, which in most cases solve the problem.
Rarer diseases, genetics, such as the Epidermolysis, where there is a defect in the adhesion between the layers of the skin, can go with bubbles.
Other autoimmune diseases, in which the bodys own defense system attacks the skin, such as lupus erythematosus, bullous pemphigoid, Epidermolysis bullosa, and others, in the same way, manifest themselves with blisters. Bacterial skin infections like pemphigoid impetigo as well. Therefore, it is very important that the dermatologist examine the patient to identify the precise cause of the bubble in question.
Some people are more likely to present blisters on their feet, by the shape of the feet, by orthopedic deformities, such as bunions, for example, that irritate more with the shoes, for diseases that the person already has, or even because the person has easy to contract ringworm.
Treating the blisters on the feet
If the bubbles have not yet burst, the ideal is not to pop them, since the bubble ceiling is the ideal dressing for your floor to heal well, preventing infection. It is important to protect the bubble with a dressing that does not stick, which can be gauze covered by liquid Vaseline, for example, or special dressings called hydrocolloids, to keep the area away from more friction and contamination.
Over time, the skin heals, the bubble turns into a cone and a new skin appears on the spot. However, when the bubble is too large, it becomes painful. In this case, it is better to take it with a sterile needle, so that the liquid will come out and stop distending the skin, causing pain. But even so, the ceiling of the bubble should not be removed, as it will help prevent the area infected. When the bubble infects, it gets filled with pus, the doctor should be searched and in this case, the treatment happens to be based on antibiotics.Based on the article above, we provide a suitable video for you regarding How does a Blister Form and How to Treat Them ( ͡° ͜ʖ ͡°)
