What is erythema?
Erythema is a strong reddening of the skin due to capillary dilatation. At the same time, this phenomenon can be both short-term and protracted, even pathological.
Let's talk more about what erythema is, what are its varieties and how to cure it.
Causes of Erythema
- Strong emotions (constraint, fear, anger).
- Physical effects on the epidermis during massage, physiotherapy and so on.
- Inflammatory diseases.
- Infectious diseases.
- Skin diseases.
- Burns (including solar).
- Exposure to high or low temperatures on the skin.
- Excessive excitation of vasoconstrictor nerve fibers.
- Increased pressure.
- Exposure to chemicals, etc.
Redness (both skin and mucous membranes) can appear as spots with clear or blurred borders. In some cases, the redness may disappear while pressing on the skin, and then return.
For certain diseases, redness may be accompanied by other negative symptoms:
- joint pain and swelling;
- fever and fever;
- rashes with papules and so on.
Types of Erythema
Among the most common forms of the disease are the following:
- Erythema nodosum. It is characterized by the appearance of nodular formations of a rich red hue (most often in the lower legs), high temperature. In many cases, the causative agent of this infectious disease is streptococci. Perhaps a chronic course of the disease with relapses in the warm season.
- Exudative erythema. These are rashes which can be any form. They appear on the legs, feet, mucous membranes, accompanied by the formation of purulent papules. Such erythema may occur due to an infectious disease (for example, herpes simplex). Often accompanied by fever with fever, body aches. In the advanced stage, the disease is fatal.
- Infrared erythema. It looks like a rash covering the skin in the form of a grid. Lower limbs are most commonly affected. Occurs under the influence of heat.
- Sudden erythema.It begins with fever, headaches and sleep disorders. After 3-4 days, these symptoms subside, and they are replaced by a rash. A few days later the rash also passes.
- Migrating erythema. In many cases, it is caused by Lyme disease, which is infectious in nature. Transmitted to a person with a tick bite. The appeared reddening in the place of a sting very actively grows.
It consists in eliminating the factor causing erythema. For example, a person refuses to visit the beach during hours of peak sun activity or stops communicating with a person who provokes negative emotions in him.
In the case when this or that pathology is the basis of rashes and redness, doctors prescribe antibiotics, medicines that strengthen the walls of blood vessels, corticosteroids, antihistamines, angioprotectors and so on. Also, diets, bed rest, exclusion of allergenic products, physiotherapy and so on can be shown.
With timely and effective treatment, the prognosis is in most cases favorable.
