A sore spot on my face?

今天早上我同事說我臉上有一個sore spot哦，怎麽回事？ 我才想起可能是趕時間沒來得及那個。I wanted to cover up my acne with makeup.結果人家以為我臉上什麽東西發炎紅腫了。What a day!

touch a sore spot and touch a sore point 點到痛處。

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.
