My sneezing problem

I have been sneezing frequently in the last few weeks. Kindly let me know what could be the cause. I am a 40-year old mother of four.

Persistent rhinitis typically causes sneezing and a blocked, itchy and runny nose. An allergy is a common cause but there are also non-allergic causes. Treatment options include avoiding things that cause an allergy, an antihistamine nasal spray, antihistamine tablets and a steroid nasal spray. Other treatments are sometimes used.
