C-Anaphylaxis
1. Lips and tongue swelling
As noted in the section about skin reactions, swelling and skin patches are common signs of skin allergies, but we should be very careful if they are located in the area of the face. Face swelling can be an alarming sign, especially when located in the area of the lips and the eyes. In many cases, this allergic reaction is associated with swelling of the tongue, which feels heavy and bigger than usual, and may even start blocking the throat and causing life-threatening problems. This is one of the first signs of anaphylaxis, and people with known hypersensitivity reactions to foods and insect bites should be extra careful when this symptom appears.
