Patients with skin allergies are advised not to drink milk. This is because the components in milk are relatively likely to exacerbate allergies, as it contains many allergens. Therefore, it is best to avoid drinking milk. However, if an allergen test is conducted and none of the components in milk cause an allergic reaction in the patient, it is safe to drink milk. Additionally, after experiencing skin allergies, it is beneficial to eat light foods and avoid rich foods, such as fish, shrimp, crab, etc.
