Hello, It seems that the symptoms of watery left eye and nose seems to be due to allergic rhinitis and it can be due to causes like allergic reaction to irritants like pollen, animal dander, dust and mites, and at times even certain trees and grasses. I would suggest you to consult an allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like Patch test, RAST test, food challenge test, etc., can help in diagnosis and treatment can be done accordingly. The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avoid exposure to prevent allergy attack. You can also take anti-allergics like Levocetirizine, Allegra, etc., along with steroid nasal sprays to relieve the symptoms. Do steam inhalations. You can also be instilled an immunotherapy that will help in reducing the severity and frequency of allergic attack. Hope I have answered your query. Let me know if I can assist you further.
