Based on your symptoms, you likely have a mild viral infection like a common cold. To help you feel better, you can take acetaminophen or ibuprofen to relieve your headache and reduce your fever. For the runny nose, an over-the-counter antihistamine like cetirizine or a simple saline nasal spray can help ease congestion. Remember to get plenty of rest and drink lots of fluids to stay hydrated. These symptoms usually improve on their own within a few days. However, if your symptoms worsen, or if your fever remains high for more than three days, please consult a healthcare professional for a personalized evaluation.

Your symptoms suggest chronic sinusitis, possibly with a deviated septum or nasal allergy, which is why you get only temporary relief and depend on sprays. Continue Montelukast + Levocetirizine as prescribed, but avoid overusing nasal decongestant sprays as they can worsen blockage over time. Do regular steam inhalation, saline nasal rinses (like neti or saline spray), and stay away from dust and allergens. Since this has lasted 3 years with one-sided blockage and headache, it?s important to consult an ENT specialist for a detailed check (like nasal endoscopy or CT scan), as you may need long-term treatment or a minor procedure for lasting relief.

A cough returning after a recent cold can be due to lingering airway irritation or a new trigger, such as dust or a weather change. Sinarest New tablet may help with cold symptoms, but may not fully control cough. Try warm fluids and steam inhalation, and avoid exposure to dust or cold air. Keep yourself well-rested and hydrated to support recovery. If the cough continues or keeps coming back, consult your doctor for proper evaluation.

Since your symptoms have lasted seven days, it is important to adjust your approach. The medications you took contain overlapping ingredients (paracetamol and decongestants), which should not be combined. Additionally, using decongestant nasal sprays for more than five days can cause rebound congestion, worsening your runny nose. Please stop these medications. Instead, use a saline nasal spray and practice steam inhalation. For relief, you may try an oral antihistamine like fexofenadine and a cough suppressant like dextromethorphan. Because these symptoms are persistent, please consult a doctor to rule out a secondary sinus or bacterial infection and get a personalised prescription. Rest well and stay hydrated.
