To relieve your symptoms, you can take paracetamol or ibuprofen for body pain and throat discomfort. For nasal congestion, a saline nasal spray or an oral decongestant like pseudoephedrine can help. If you have a dry cough, dextromethorphan is effective, while guaifenesin helps clear a productive cough. Throat lozenges and warm saline gargles will also soothe irritation. Please get plenty of rest, stay well-hydrated, and follow the dosage instructions on the medication packaging. If your symptoms do not improve after a week, worsen, or if you develop difficulty breathing, please consult a healthcare professional in person for a proper evaluation. Get well soon!
