Can severe coughing cause anything?

A sore throat.

My brother had a extremely bad cough for at least a few weeks a while ago, it was like a chesty cough and all you heard throughout the day was him constantly coughing. It shouldn't be anything to worry about, but depending on how long you have it for, you should go to the doctors if for a while.

Coughing won't cause anything. Others cause it. No need to worry. They're usually a pain in the butt to treat and can linger around for a long time even with medication.

As User above me said, won't cause anything.

However if it's harsh and continuous it could begin to affect the throat lining and the stomach lining to an extent. Definatley get it checked out by your GP.
