You can relieve cold and flu symptoms by resting, staying hydrated, using paracetamol for fever or aches, and saline nasal sprays for congestion. If symptoms persist for more than a week or worsen, consult your doctor for an evaluation.

You can try warm saline gargles, honey with warm water, and steam inhalation to soothe throat pain and relieve coughing. Staying hydrated, resting, and using over-the-counter cough syrups or lozenges can also help, but consult your doctor if symptoms are severe or persistent.
