A corn can appear on any part of the body covered in skin. After all, they can be generated by uncomfortable shoes, new or not suitable in size.
As for the hands - here they can appear during active work with various tools, for example. Perhaps everyone knows what corn is, because everyone has come across them repeatedly. However, what is the mechanism of their appearance? Do I need to consult a doctor with them, and are there secrets to exclude the appearance of blisters? All this is worth talking in more detail. After all, the problem is really relevant.
Causes of Corns
The skin has many functions. And in particular, they provide protection to those tissues that are under them and have greater sensitivity. That is why the skin on the soles, for example, is rougher than on other parts of the body. After all, there are more loads on these parts of the body.
The skin in the armpits, on the contrary, is distinguished by tenderness, this zone usually does not experience heavy loads or strong friction. Because the skin here is subject to irritation, if you choose, for example, a narrow shirt.
However, the strength of the skin and its resistance to external influences is not absolute even in those areas where it is dense, rough. There are limit loads for everything, and when exceeded, damage and calluses begin to appear on the skin. Damage does not appear instantly.Everyone knows that new shoes can seem quite comfortable and convenient from the beginning, and the reverse side of wearing can manifest itself in a few hours.
In order for corn to appear, pressure and friction are necessary. In this case, skin cells are gradually damaged. The epithelium, that is, the surface of the skin, can remain intact, but the cells of the middle layer will be destroyed, and all the liquid from them will accumulate under the epithelium. A peculiar pillow of liquid will appear, which we used to call corn. It can hurt, but the very presence of a bubble of water will rule out deeper tissue damage if pressure and friction continue.
What can be corns?
Corns may be different. The variant with liquid already considered above occurs when cells are damaged, lymph and cellular fluid flow out. Sometimes bloody corns occur - in such cases, along with these fluids, the bubble is also filled with blood. Blood is taken from small vessels that were destroyed by friction. Indeed, in the deep layers of the skin they are.
Separately, it is worth talking about dry corns. If wet or bloody corns appear several times in the same place, the skin there becomes more rough and dense. Additional layers of the epithelium intended for protection are growing, because the body perfectly understands that the permanently damaged place needs special protection.
As a rule, there is no pain or discomfort from them, but in some cases people tend to get rid of them so that the hands or feet remain tender and attractive. There are many ways to get rid of corns, for this they turn to beauty salons and doctors.
Interesting fact: see a doctor because of the callus can be very relevant. So, for example, bloody corns tend to fester, they require special treatment. At the emergency room or at the doctor's office, they will help you and treat all skin lesions as necessary.
What to do to exclude the appearance of corns?
In fact, it is quite possible to reduce the risk of corns. To do this, you should carefully approach the choice of shoes and clothes, focusing only on those models that are really comfortable. Soft materials and a suitable size will relieve discomfort. This is true for shoes for the summer, because corns are most easily formed on sweating or swollen feet.
Hand and foot care also benefits, improves the protective qualities of the skin, helps to cope with external negative influences. It is also worth using work gloves if you are holding on to a tool.
Thus, corns appear from rubbing or pressure, in cases where the cells of the middle layer of the skin are destroyed by external influences. Despite the fact that corns usually pass by themselves, sometimes they have to consult doctors.
