Allergy is a common symptom.
But if an allergy becomes severe, it can potentially endanger a person's life.
Among the patients Liu Banxia has received, there have already been several with extremely severe allergies, and in every case, tracking down the allergen has been very labor‑intensive.
For example, that patient with an immunological disease messed up her endocrine system because she took birth control pills. And that patient allergic to copper—turns out the problem was her IUD.
This patient, even before a formal history-taking, you can tell her situation is definitely very complicated.
Someone with a highly sensitive constitution will be extremely careful in daily life, keeping all possible allergenic factors far away from her.
Her boyfriend naturally knows this too, so he's just as careful.
Yet even so, an allergic reaction still occurred.
