So, why can pimples appear on the hands? Various allergic reactions, eczema, urticaria - all these manifestations may indicate malfunctions in the internal organs. Which ones, the doctor will tell you. In addition, skin rashes can be the result of external factors (for example, irritation from active chemicals or sunburn). The biological factor can also affect the skin condition not in the best way: bacteria, viruses, fungi - all this affects, first of all, the skin integuments and nails.
Any specialist will confirm that when making a diagnosis one should not lose sight of the possibility of diseases of the internal organs, lesions of the vascular system, foci of local infections. Thus, pimples on the hands are a rather serious problem, and you should not leave it unattended.
Skin pathology
All the ailments described above are reflected on the human skin: all kinds of inflammations, pigmented spots, nodules, seals, small rashes in the form of vesicles, water vesicles with various contents (pus, anemone), and finally, pimples on the hands.
Dyshidrosis
In most cases, marks on the skin of this kind indicate dyshidrosis. This disease can be both independent and a sign of other skin diseases. The main symptom of dyshidrosis is small vesicles (about the size of a pinhead) filled with transparent contents. Most of the bubbles, as a rule, covers the palms, feet. Thus, the notorious pimples on the hands, most likely, can be explained precisely by dyshidrosis. As for the causes of the disease, they have not yet been established. Most dermatologists agree that the origins of the problem should be sought in the endocrine system. For many people, the disease worsens in the autumn and spring.
Dyshidrotic eczema
Pimples on the arm can be caused not only by dyshidrosis, but also by dyshidrotic eczema. How to distinguish one from the other? Eczema is primarily distinguished by acute development after the patient's contact with substances that irritate the skin (detergents, washing powders, creams, lotions), stress, emotional upheaval. Hands swell strongly, redden, become covered with vesicles that gradually burst, the field of which swelling only intensifies (this is due to the addition of a secondary infection). In addition, the patient may experience an increase in lymph nodes under the armpits. Many patients complain of fever, general weakness, painful manifestations. Dyshidrotic eczema, occurring once, often returns for no apparent reason.
True dyshidrosis
If the pimples on the fingers are caused by true dyshidrosis, they last about ten days, after which they dry up or burst (this is accompanied by the release of serous fluid). Opening of the vesicles may be accompanied by acute pain, but new formations do not occur.
Other diseases
Skin problems can be caused by chronic eczema, smallpox, scarlet fever, typhus, and sexually transmitted diseases. In any case, such symptoms require immediate contact with a dermatologist.
