Your symptoms suggest allergic rhinitis, an immune overreaction to allergens like dust. To prevent this, minimize exposure by using air purifiers, washing bedding in hot water weekly, and wearing a mask while cleaning. For home remedies, use saline nasal sprays or steam inhalation to relieve congestion. For treatment, over-the-counter non-drowsy antihistamines (like Cetirizine or Loratadine) effectively control sneezing and itching, while steroid nasal sprays (like Fluticasone) help reduce inflammation. Please consult a healthcare provider for a confirmed diagnosis before starting new medications.
