I recently tested positive for dust-mite, tree, and grass allergies. My primary symptoms are daily fatigue/malaise, intermittent headaches (temple and bridge-of-nose), slight nasal congestion, eustachian tube dysfunction, and lightheadedness. I often feel feverish, but whenever I take my temperature it is normal (98.4). I also occasionally get an itchy throat, burning eyes, dry mouth, increased thirst, and frequent urination.
