Hi,
The symptoms that you are showing are typical of "Allergic Rhinitis". In other words, your body's defence mechanism is not strong enough to fight the allergens entering the body from outside.
Next Steps
You need immunity boosters or the herbal combinations that are said to improve the immunity, which in your case is weak.
