If many red spots appear on the back of your hand, you should pay attention to it. It may be caused by some skin diseases. The most common one is allergy. For example, mosquito bites and pollen dust irritating the skin may cause allergies. Of course, it may also be a bleeding spot. You can judge it if you press the red spot with your hand and let go for 1 to 2 seconds. If the redness does not disappear, it may be a bleeding spot. If it is a bleeding spot, you should go to the hospital for examination in time.

Why are there so many red spots on the back of my hand?

1. First, rule out recent infection; if you are pricked by a needle or something, many people take a long time to understand what is going on. If this happens, it will hurt when you press on the area, the surface will turn red, and you will see something in the middle. Some deeper ones can be checked out at the hospital and surgically removed.

2. Allergies: Allergies caused by mosquito bites are common and not uncommon. They can be treated according to the allergy treatment. I will not go into details here.

4. Spider nevus. As the name suggests, it is not difficult to imagine that if there is only one occasionally, it is fine. If there are multiple spider nevus on the body, liver function problems should be considered;

5. Vascular nevus: This is more complicated. Many people have it on the back of their hands. They are often more common. When pressed, the red spots disappear and reappear after two or three seconds. This type of nevus is harmless to the human body in most cases. Microwaves or lasers can remove it.

6. Hemangioma; some people call it hemangioma. The reason why it is listed separately is that some of them are small red bags protruding from the skin. This is a hemangioma, which is generally very small and occasional, so you don’t need to pay attention to it.

7. Folliculitis: This is similar to the first one, but if folliculitis is not properly treated, it will form a small red dot-like thing; it is actually local capillary hyperplasia; it is harmless to the human body and can be easily removed by microwave or laser;
