You are suffering from allergic rhinitis and all symptoms appear to be due to that. High eosinophils are also due to allergy and not vice versa. Take an antihistamines like cetirizine once or twice a day, montair10 once a day and use Flonase nasal spray twice a day. Deform your self with zental400, one tablet at night for 3 days.  You should improve with these. Take care.
