What is the reason that arm rises red dot

summary

Recently, during the summer vacation, I went to the suburbs. After I came back, I found many little red spots on my arms. I usually don't feel itchy, and I don't feel pain when I touch it. Later, there was no spreading phenomenon. It has been two days on my two arms, and I don't feel any signs of fading. Let's have a look.

What is the reason that arm rises red dot

First: many kinds of situations can lead to small red spots on the skin. The more common one is caused by allergy, such as seafood allergy, pollen allergy or other allergies. There is also a possibility that folliculitis caused by hair follicle blockage can also cause red spots on the skin, and it may also be purpura.

Second: if the red spots appear in the pores, and these red spots are slightly raised, we should pay attention to the possibility of folliculitis, whether the pores are blocked or other conditions. At this time, you can ask your family, because there will be some heredity.

Third: if it is purpura, it does not have much impact on itself, because purpura is essentially the rupture of capillaries. After a period of time, the color will become lighter until it subsides. If it is purpura, you can rest assured that it will not cause too serious damage.

matters needing attention

When these unknown red spots appear, the most important thing is to find out the reason, and then carry out symptomatic treatment according to the reason. Don't rashly take inappropriate measures to aggravate the disease.
