Pollen allergies develop in humans due to the natural reproduction for plants which is done through pollination with the help of the wind. Often, pollen allergies are referred to as ‘hay fever’ because people noticeably suffer from them during haying season, but a pollen allergy can happen in spring, summer or fall because various plants pollinate at different times of the year. Symptoms can vary depending on general climate and how severe the reaction is to different types of pollen. Pollen allergies can be difficult to identify because the symptoms are very similar to other types of allergy symptoms like those that are noted with pet dander and mold.
Generally, the symptoms of pollen allergies include itchy eyes and skin, a stuffy nose with the possibility of nosebleeds. Sometimes this leads to trouble breathing. Often headaches are included in the list of symptoms, as are sore throat and dark circles under the eyes. Symptoms can also include coughing and wheezing as well as asthma attacks. Increased congestion is a frequent symptom, along with sneezing and runny nose. Feeling tired and weak or drowsy is one of the more common symptoms. However, sometimes food allergies are mistaken for pollen allergies.
Some of the differences include rashes and hives in food allergies in addition to itchy skin, or not just sneezing, but watery eyes and an itchy throat at the same time. Food allergies can also cause nausea, burping, vomiting or diarrhea, where usually pollen allergies do not. Sometimes food allergies increase allergic asthmatic reactions to dust and mold and make them worse without the symptoms being obvious right after eating the food.
Pollen allergies are the main allergies in the United States, especially during the seasonal allergy months, which are spring and summer. Wintertime is usually less of a problem for allergy sufferers, but there are still some plants that release pollen in the middle of winter. Because the symptoms often mimic other types of allergies, it is a good idea to visit a doctor to determine exactly what kind of allergy you are suffering from so that you can get proper treatment. Though you may want to, you really can’t diagnose yourself, and may try to treat one allergy with the remedy for another, which usually doesn’t work. All in all, pollen allergies are suffered by many people, and there are various effective treatments to help, but you should visit an allergy specialist to be evaluated and properly treated for the specific type of allergy you may have.

Generally, allergy shots are safe, with minimal side effects. There are no long-term complications associated with this form of therapy, but there is a small risk of allergic reactions immediately following the injection. These allergic reactions can be severe.
Typically, allergy shots may cause slight swelling or redness at the injection site. These reactions can occur immediately after the injection and/or can occur several hours later. This mild allergic reaction is usually harmless and goes away within 24 hours.
The shots may also cause symptoms similar to the allergy symptoms you experience: itchy, stuffy nose; itchy, watery eyes; sneezing. In very rare cases, these symptoms become very severe and are accompanied by other symptoms, including the following, difficulty breathing or wheezing, chest or throat tightness, rapid or irregular heart beat, dizziness or light-headedness, loss of consciousness and death.
This type of very severe allergic reaction is known as anaphylaxis. It is a very uncommon reaction to an allergy shot, but it is dangerous, even life threatening.
This is less likely to happen if you follow the schedule of shots recommended by your allergist and observe the technician administering the shot. Be sure you are receiving the correct dose of the correct extract. The dizziness, light-headedness, and loss of consciousness are due to dangerously low blood pressure, usually called “shock.” These symptoms occur when the brain is not receiving enough blood. Anaphylactic shock is a medical emergency.
Such severe reactions usually begin within 20-30 minutes after receiving the shots. For this reason, most allergists require that you wait in the office for 20-30 minutes after your shots to be monitored. If you should experience these symptoms at any time, tell the allergist or other medical professional right away.
If you have already left the allergist’s office, and are having a severe reaction, go directly to the nearest hospital emergency department. If you already have and Epi-pen, use it. If you have an antihistamine such as Benadryl, take it regardless, go to the nearest hospital emergency room or urgent care center as soon as possible. Do not attempt to drive yourself. If no one is available to drive you immediately, call 911 for emergency transport.
Immunotherapy does not treat symptoms; it treats the immune system, the source of all allergic reactions. Although the exact details of how allergy shots work is unknown, we do know the general way they affect the immune system.
An allergic reaction occurs when the body is exposed to an external substance (the antigen) that the immune system interprets as a foreign invader. In allergic individuals, the immune system then makes an unusual (allergic) response that harms the body.
Allergy shots desensitize you by turning down this immune response to the antigen. As a result of immunotherapy, the white blood cells no longer respond as strongly to the antigen, and less production of the immunoglobulin E antibody to this antigen occurs. So, when you are exposed to this antigen, less severe allergic reactions occur in affected areas like the eyes, nasal mucosal surfaces, and the bronchial airways.
