问我儿子1岁9个月了,在他三四个月的时候,右嘴角旁边约1厘米的地方长了一个米粒大小的印,这个印的颜色只比肤色深一点,不高于皮肤。但是,我发现这个印有时会变成一个红疙瘩,像被蚊子咬过,但他好像感觉不疼也不痒。现在随着年龄的变化,这个印已经有绿豆大小了,颜色也较以前深了一些。发作的时间和次数都不定,有时候一天一次,有时候几天甚至半个月发作一次。我们找医生看 My son was 1 year and 9 months old. When he was 34 months old, he had a grain-sized print about 1 centimeter by the right corner of his mouth. The color of the seal was only a little deeper than the skin tone, not higher than the skin. However, I found that this print sometimes turns into a red pimple that is bitten by mosquitoes, but he does not seem to feel pain or itch. Now with the change of age, this print already has a mung bean size, and the color is deeper than before. The timing and frequency of attacks are uncertain, sometimes once a day, sometimes a few days or even half a month attack. Let’s see the doctor
