why does my cough vibrate?

[PeterSilas]

I'm a doctor, and I agree with user. The vibrating cough may possibly be because of the mucus in your chest. It could be a symptom of bronchitis or pneumonia. Let me put up some symptoms of bronchitis:

1. low fever and chills
2. headache
3. shortness of breath
4. mucus-producing cough
5. chest pain

however, on-line information should in no way replace an actual consultation. You must visit a healthcare specialist.
