If you have had a cough for more than 3 weeks, it may be a sign of a bacterial infection and you should see a doctor. Symptoms of pneumonia include fever, chest pain, difficulty breathing, increased heart rate, and feeling generally unwell. However, if your symptoms have been present for less than 3 weeks, you can try resting, staying hydrated, using a saline nasal spray, continuing any prescribed medication, soothing your throat with honey, and gargling with salt water as needed for its antiseptic properties. Hopefully, these tips will help you feel better soon.
