My face is swollen after visiting the Korean medicine clinic.

One day, I don't think I ate or applied anything wrong, but suddenly my skin swelled up and a part of it itched, just like an allergic reaction to sunscreen. I talked to Gemini about it, and we learned that the cupping therapy I received at a traditional Korean medicine clinic might have been the cause. They told me that even though it wasn't my first time, there could be a mechanical allergy. So, I took an antihistamine, and I felt better immediately. It was such an unfamiliar experience, so I am writing it down.
