Red spots on the back of hands and arms

Because most of the red spots will make people feel itchy, when people find small red spots on the back of their hands and arms, they often look for many reasons that may cause the small red spots on their arms. Although the skin on the back of your hands and arms is not as fragile as the skin on other parts of your body, you should not scratch it excessively after the small red spots appear. The main reasons for the small red spots on the back of the hands and arms are as follows.

Causes of red spots on hands

1. Eczema is an inflammatory reaction of the skin with polymorphic skin lesions and a tendency to exudation caused by a variety of complex internal and external factors. The cause of this disease is complex and difficult to determine. The subjective symptoms are severe itching, and the disease is prone to recurrence and may not be cured for many years.

2. Urticaria is a localized edema reaction caused by dilation and increased permeability of small blood vessels in the skin and mucous membranes, commonly known as "wheals". It is characterized by the appearance of white or red rashes on the skin, which occur suddenly, have no specific location, appear and disappear from time to time, and are extremely itchy, and disappear without leaving any traces.

3. Scabies is a skin disease caused by scabies infecting the skin (mechanical damage from digging tunnels and stimulation from their venomous juice secretion). It can be transmitted through sexual intercourse, especially among young men and women who engage in promiscuous sex. The disease spreads rapidly, so it has been listed as a sexually transmitted disease by the World Health Organization. The signs of scabies are intense itching of the skin, and the rash often occurs in the folds of the skin, especially in the pubic area. Scabies is a disease that is spread through close contact. Scabies is highly contagious and is often transmitted from one family to another or from one dormitory to another. Scabies can live outside the human body for 2 to 3 days. Therefore, using clothes, bedding, shoes, socks, hats, and pillowcases used by patients can also be indirectly transmitted. Sexual intercourse is undoubtedly a major route of infection.

4. Scabies is a tiny insect that is invisible to the naked eye. There are countless horizontal wavy wrinkles on the back of the scabies mite, several pairs of rod-shaped bristles and long bristles on the posterior half of the trunk, four pairs of legs on the abdomen, and the anus is in the center of the posterior edge of the trunk. The palate of scabies is very small, located at the front end of the trunk, half of which is sunken into the trunk. The chelicerae are pincer-shaped, which are suitable for eating the keratin of the skin. Parasitic in the human epidermis.
