Human skin is very sensitive to both internal changes in the body and external influences. A rash on the arms and legs is the body’s reaction to the influence of various factors, so it’s simply impossible to say immediately about the causes of its appearance. In any case, it is best to consult with a specialist who, after an initial examination and taking several tests (if necessary), will determine with accuracy why skin rashes appeared.
The causes of a rash on the hands may vary. Let's look at the most common ones. The first and main is an allergy, which can occur both under the influence of external and internal factors. That is, small pimples on the skin are a reaction to pet hair, detergents or cleaners, cosmetics or food, drinks, medicine, and more. It should be noted that with such a disease, the rash usually occurs in a small area, not particularly spreading to large areas. She can appear in absolutely any place.
External causes of a rash on the hands are the penetration of infectious pathogens, that is, bacteria, through the broken integrity of the upper skin integument into the body, for example, through a wound. Such a manifestation can often be observed in those who are engaged in physical work, where the hands are constantly in a dirty state, but there is simply no way to wash them.
In this case, a small rash appears, which causes a lot of inconvenience due to the fact that it causes severe itching. In addition, severe redness in the affected area and even swelling may occur, but a small area of the skin is also affected by the infection.
The causes of the rash on the hands, as well as on the neck, face, buttocks and in the folds of the skin, characterized by extensive rashes and severe itching, can be various. In the presence of small rashes only on the hands, we can talk about contact dermatitis, which is caused by an allergic reaction to any drug, such as an abrasive detergent. If redness and rash are spread throughout the body, then this is atopic dermatitis, which can be not only acquired, but also hereditary. In addition to itching, there is also dry skin, and profuse peeling in places of its occurrence. If such a disease is left unattended, this will lead to the skin becoming roughened over time, and the treatment will be especially difficult and lengthy.
If you have a colorless rash on your hands that looks more like goosebumps, then this is most likely a reaction to some medicine or food product. Most often, such a rash does not bother its owner with irritation, peeling and itching, so they usually notice it not immediately. However, the causes of a rash on the hands of a color similar to flesh may not be so simple. As practice shows, the following diseases can begin in a similar way: dermatitis, psoriasis or eczema. In any case, with a similar problem, you must definitely contact a dermatologist.
Prior to contacting specialists, no treatment on their own is necessary, but it is possible to calm the itching and irritation. In this case, cold lotions and compresses will help you. For a more effective effect, you can use a cold decoction of chamomile and even ice cubes.
