The sensation of itching is one of the types of skin analyzers, similar to such forms of skin sensations as touch, burning, tingling, pain, in which there is a physiological reflex of scratching the skin.This article will tell you in detail about the types, causes and treatment of folk remedies of localized itching of the skin, providing the text with useful photos.

What is localized pruritus

Along with pain, itching performs an extremely important function of protection, being a sign for the immediate elimination of substances that damage the skin. Itching localized, unlike generalized( spread), develops on a limited area of ​​the skin.

  • Condition of itching - unpleasant, irritating, similar to painful - is provoked by mechanical, chemical, thermal, electrical stimulation of nerve fibers emerging in the border area between the epidermis and the dermis.
  • Excitation of nerve endings occurs either directly or indirectly - when releasing mediators such as histamine, adrenaline, serotonin, kallikrein
    , neuropeptides, opioids, cytokines, eicosanoids, and also in the presence of helminthic, tick-borne, tumor and other toxins.
  • If the pain causes a natural reaction of "removing" from the source, itching affects the person as an irritating skin "object", which must be eliminated.It provokes a reflex of "treating" the itching area in the form of carding, rubbing, tweaking, which leads to quick, but brief satisfaction.

This is explained by the fact that in the process of combing the nerve endings receive stronger pulses, suppressing weak signals from itching.Intensive painful itching, for example, with neurodermatitis, patients often relieve, causing severe damage to the skin, tearing it, which leads to the replacement of severe itching with a feeling of severe pain.
