If there are a few small red spots on your arms without any symptoms and no impact on your health, you don't need to worry about it and no treatment is required. If the small red spots on your arms are higher than the skin surface and have stretched capillaries, it may be caused by cirrhosis of the liver and you should go to the hospital for examination and treatment. Some red spots are as small as a needle tip, which may be caused by purpura. You should pay attention to prevention and care in your daily life.

Why are there so many red spots on my arms?

Red spots appear on the skin and are often very noticeable. These red dots have different properties, so be careful to distinguish them. The most common red dots are red moles that are as small as a needle tip or as large as a sesame seed, and are slightly raised above the skin surface.

In fact, red moles, like black moles, have no effect on health. Unless there are recent and obvious changes, no treatment is usually needed.

The cause of many red spots on the arms

1. There is a type of nevus in which the center is slightly higher than the skin surface and there are many capillaries extending outward around it. This is called a spider nevus. It is mainly seen in patients with cirrhosis and treatment should be targeted at the cause.

2. Another type of red spots on the skin are manifestations of subcutaneous bleeding, which are bright red at first, gradually turn purple after 2-3 days, and then turn yellowish brown, and eventually disappear without leaving any trace.

3. Subcutaneous bleeding as thin as a needle tip is called petechiae. Larger ones are called purpura. Those with a diameter of more than 0.5 cm are called ecchymosis, commonly known as black and blue lumps. Petechiae are sometimes seen in some acute infectious diseases, such as epidemic meningitis and some serious bacterial infections, such as sepsis and subacute bacterial endocarditis.

4. In addition, the causes of subcutaneous bleeding can be attributed to two factors: vascular factors and platelet factors.

Purpura prevention and care

prevention

1. Actively participate in sports activities to enhance physical fitness and improve disease resistance.

2. Try to find out the various causes of allergic purpura as much as possible. Actively prevent and treat upper respiratory tract infections, control tonsillitis, tooth decay, and sinusitis, expel various parasites in the body, and avoid foods and drugs that are likely to cause allergies.

3. For thrombocytopenic purpura, attention should be paid to preventing respiratory tract infections, measles, chickenpox, rubella and hepatitis, otherwise it is easy to induce or aggravate the disease.

Nursing

1. During the acute phase or when the amount of bleeding is heavy, the child should rest in bed, limit his or her activities, and eliminate his or her fear and tension.

2. Avoid external injuries, falls and collisions to prevent bleeding.

3. When the platelet count is lower than 20x109 times/L, closely observe the changes in the condition to prevent various traumas and intracranial hemorrhage.

4. The diet should be light, nutritious and easy to digest. Those who suffer from vomiting blood or bloody stool should eat a semi-liquid diet and avoid hard food and coarse fiber food. Avoid spicy food. Sons with thrombocytopenic purpura can eat more foods such as peanuts with skin and red dates.
