If you are experiencing coughing with a little bit of blood, it is important to monitor it and see if it persists for more than 3 to 5 days. If the blood persists or if the amount increases, it may be necessary to speak to a doctor. Coughing can be caused by mucus drainage in the throat, which is often relieved by nasal hygiene with a saline solution. Additionally, if you are experiencing ear pain and a feeling of blockage, using a nasal decongestant spray may offer relief. It is also recommended to use a humidifier in your home to help with any dryness or irritation caused by heating.
