A sore spot on my face?

今天早上我同事说我脸上有一个sore spot哦，怎么回事？ 我才想起可能是赶时间没来得及那个。I wanted to cover up my acne with makeup.结果人家以为我脸上什么东西发炎红肿了。What a day!

touch a sore spot and touch a sore point 点到痛处。

Fig. to refer to a sensitive matter that will upset someone. (Fig. on the notion of touching an injury and causing pain.) I seem to have touched a sore spot. I'm sorry. I didn't mean to upset you. When you talk to him, avoid talking about money. It's best not to touch a sore point if possible.
