[|Human|] I am suffering from unknown allergy (symptoms: heavy itching in mouth near upper pallette and ears) leading to periodic  nasal congestion, septum infection and if untreated results into fever and respiratory symptoms like chest tightness, twitching, irregular chest pain. I am tired of drugs like Allerid-D 10 mg and drugs by a family physician. I need to sort this out, as it has lead to poor immunity and unhealthy lifestyle.
