Why do I have chest tightness, breathing difficulties

Condition analysis:
Hello. Your condition is the asthma symptoms caused by allergies. An allergic response occurs when immune system proteins (antibodies) mistakenly identify a harmless substance, such as tree pollen, as an invader. In an attempt to protect your body from the substance, antibodies bind to the allergen.

The chemicals released by your immune system lead to allergy signs and symptoms, such as nasal congestion, runny nose, itchy eyes or skin reactions. For some people, this same reaction also affects the lungs and airways, leading to asthma symptoms.

Instructions:
Leukotriene modifier.
Montelukast (Singulair) can ease both allergy and asthma symptoms. Called a leukotriene modifier, this daily pill helps control immune system chemicals released during an allergic reaction. In rare cases, montelukast has been linked to psychological reactions, including suicidal thinking. Seek medical advice right away for any unusual psychological reaction to one of these medications.

Allergy shots (immunotherapy).
Allergy shots can help treat asthma by gradually reducing your immune-system response to certain allergy triggers. Immunotherapy involves getting regular injections of a tiny amount of the allergens that trigger your symptoms. Your immune system builds up a tolerance to the allergens over time, and your allergic reactions diminish. In turn, asthma symptoms decrease as well. This treatment generally requires regular injections over a period of three to five years.

Anti-immunoglobulin E (IgE) therapy.
When you have an allergy, your immune system mistakenly identifies a specific substance as something harmful and releases antibodies, known as IgE, against the culprit allergen.
