I cough a lot, and it hurts my lung. I don't have a fever. What should I do?

If you're experiencing symptoms and are unsure of what to do, it's important to first assess your symptoms and check if you've been exposed to any potential sources of infection. If you believe you may have been exposed or if your symptoms worsen, it's recommended to contact a healthcare professional for further guidance. It's important to follow proper hygiene measures, including staying home if you are feeling unwell, to help prevent the spread of illness to others. Remember to stay informed and not panic, as most cases of illness can be managed with proper care and precautions.
