When someone with a milk allergy consumes milk or dairy products, their immune system mistakenly identifies the proteins in the milk as harmful invaders and releases histamines to fight them off. This immune response can cause inflammation and swelling in various parts of the body, including the face. The swelling is a result of increased blood flow and fluid accumulation in the affected area, leading to the characteristic puffiness or swelling of the face. **

When you are allergic to a particular substance, such as an insect sting, your body's immune system overreacts to the allergen. This triggers the release of histamine and other chemicals, causing inflammation, swelling, and other symptoms at the site of the sting. The swelling is part of the body's defense mechanism to isolate and remove the allergen, but in the case of an allergy, the response is exaggerated and can lead to more severe swelling and discomfort. It's important to seek medical attention if you experience a severe allergic reaction to a sting. **
