Most colds and coughs are caused by viruses and usually resolve on their own. The treatment should focus on relieving symptoms and supporting recovery, including staying hydrated, getting adequate rest, using a humidifier, and maintaining a healthy diet. It is essential to consult a healthcare professional if symptoms are severe, persistent, worsening, or associated with high fever, difficulty breathing, or underlying health conditions, so they can assess for bacterial infection or other causes and recommend safe, targeted treatment. Medications should only be taken under a doctor’s guidance.

Blocked nose, throat pain, fever, and persistent cough may be due to a viral or bacterial infection. Drink plenty of fluids, rest, and use warm saline gargles for throat pain. Over-the-counter fever and cough medicines can help, but if the fever is high, the cough lasts more than a week, or you have difficulty breathing, see a doctor promptly for proper diagnosis and treatment.
