5. Chest pain
Chest pain occurs because of sore ribcage muscles from coughing, and partially because of pleural inflammation (pleurisy), which is the tissue between the lungs and ribcage. Severity of this symptom can vary, with some patients perceiving it as a mild inconvenience, while others report not being to sleep at night or move without excruciating pain. Sometimes patients interpret it as a heart attack, which can be traumatic.
6. Nausea, Vomiting, Abdominal cramps
Intense coughing may trigger a gag reflex causing vomiting and nausea. Also, due to water loss through sweating and fever, some patients complain of abdominal cramps. These symptoms can last up to 7 days, but typically resolve faster.
