Question:
I have a severe cough, green phlegm, and a runny nose. What possible conditions could be causing this? I have been taking medication prescribed by the hospital, but it hasn't been effective at all. I haven't had a fever, and I felt chills for a brief moment, but they went away quickly.
Answer:
I understand your concern, especially since your severe cough, green phlegm, and runny nose are persisting despite taking your prescribed medication.
Based on your symptoms, here are a few possible conditions:
Bacterial Sinusitis: Characterized notably by the presence of thick, green phlegm or nasal discharge.
Bronchitis: A persistent cough and phlegm are the primary symptoms.
Allergic Rhinitis with a Secondary Infection: An underlying allergy that has developed a secondary bacterial complication.
Pertussis (Whooping Cough): This can be suspected if a severe, uncontrollable cough persists.
Mycoplasma Pneumonia: This type of respiratory infection can present with severe coughing even in the absence of a high fever.
Because you are continuously coughing up green phlegm and your current medication is not bringing relief, you may require a different treatment plan, such as a course of antibiotics.
I strongly recommend scheduling a follow-up appointment with your doctor for an in-person re-evaluation. In the meantime, please seek immediate medical attention if you develop any of the following warning signs:
Repeated vomiting triggered by the coughing
Blood mixed in your phlegm
Shortness of breath, wheezing, or chest pain
Symptoms that persist for more than 10 days without any sign of improvement
