Your current spray is a saline (saltwater) solution, which is great for moisturizing but often insufficient for chronic congestion. For stronger, more effective relief, you may want to discuss nasal corticosteroid sprays, such as fluticasone or mometasone, with your doctor. These target and reduce inflammation in the nasal passages and are safe for daily use. If allergies are the cause, an antihistamine spray like azelastine might also help. Because your breathing is affected, please consult a healthcare professional. They can examine your nasal passages to identify the underlying cause and prescribe the safest, most effective treatment for you.

Head heaviness with one-sided nasal blockage and dryness can happen with Sinusitis, allergies, a common cold, or nasal irritation. Sinus congestion can sometimes also trigger cough due to post-nasal drip. Steam inhalation, saline nasal spray, hydration, and avoiding dust or smoke may help reduce dryness and blockage. Since the congestion is mainly on one side, an ENT examination may be needed if symptoms persist, worsen, or are associated with fever, facial swelling, severe headache, or thick nasal discharge. Avoid using nasal decongestant drops continuously without medical advice. A doctor can decide whether you need allergy treatment, nasal sprays, or other medicines after proper evaluation.
