Allergies can be seasonal or year round. Hay fever caused by pollen is the most common seasonal allergy. Symptoms include:
- Stuffy/runny nose
- Itchiness in the nose and throat
- Postnasal drip
- Itchy, watery eyes
- Pressure in the ears
Year-round allergies produce the same symptoms, but come from things like mold, dust mites, smog, smoke, and pet dander. Insect bites and stings also fall into this section. They can produce a life-threatening allergic reaction known as anaphylaxis.
Medications are available to help with the allergies and provide symptom relief. If allergies do not respond to medical treatment, then a person may be given immunotherapy (allergy shots) to try to build up one’s tolerance to the offending substance. These shots occur through several injections for several years.
