Allergic Rhinitis
Allergic rhinitis [2] (or hay fever) is an inflammation of the insides of the nose caused by exposure to an allergen. Many things can trigger this reaction. Some of the most common triggers of allergic rhinitis are dust, pollen, mold or skin flakes from some animals.
It often causes symptoms that resemble cold such as sneezing, a blocked or runny nose, and itching of the nose, palate and eyes. These symptoms start shortly after exposure to an allergen. In most people, the symptoms are mild and can be treated easily. In some people, the symptoms may be persistent and severe, sometimes disrupting their everyday life.
The symptoms can be relieved in some cases, but the condition scarcely ever completely disappears. If your rhinitis interferes with your everyday life, you should see your doctor.
Swollen Lips, Tongue, or Face (Angioedema)
Some allergic reactions may trigger a condition known as angioedema [3]. Angioedema is swelling that happens under the skin in reaction to medicine or allergens. It usually affects the lips, tongue, hands, and the skin around the eyes.
Angioedema is not a serious problem in most cases, but it can be persistent in some people. The swelling can also cause breathing problems which can be life-threatening sometimes. Thankfully, some treatments can help keep the swelling under control.
