What should I pay attention to when I have small red spots on my arms?

1. Don’t scratch: Most people’s instinctive reaction to itchy skin is to scratch it with their hands, but you may not know that this action not only fails to relieve the itching, but may make it worse. This is mainly because when you scratch the area, it increases the local temperature and causes the blood to release more histamine (allergens), which will make the condition worse.

2. Don't use hot compresses: Some people want to use hot compresses when they feel itchy. Although heat can make the local itching sensation temporarily less sensitive, it is actually another kind of stimulation because heat can dilate blood vessels and release more allergens. For example, soaking in an overheated hot spring or bathtub, or wrapping in a heavy quilt to keep warm are all likely to cause urticaria.
