Runny nose, dry cough, and throat congestion for a few days are often caused by a viral infection. Antibiotics may not give quick relief if the cause is viral. Drink warm fluids, try steam inhalation, and rest your voice to soothe the throat. If symptoms continue or worsen after a few more days, consult a doctor for proper evaluation.

If you notice small streaks of blood in your sputum occasionally, especially in the morning, it can sometimes be due to throat irritation, dry air, or forceful coughing. However, if it persists or worsens, you should see a doctor for evaluation.
