10 Signs You Could Have Allergies

7. Swelling

If you react to an allergen by swelling, this can be dangerous. In some cases, your throat and lungs could be at risk, reducing your ability to breathe. In most cases, severe swelling occurs due to insect bites, food allergies, a reaction to medication, or pet dander.

If you notice that your fingers, tongue, and lips begin to swell, you may be having a reaction. If you notice that your throat is swelling, call an ambulance and take an antihistamine if possible. If this has happened before, it's important to discuss emergency options with your doctor - such as an EpiPen or an inhaler for future use.
