I'm kinda worried about my mum because she keeps coughing really badly and it's like, gagging after she coughs which makes me feel sick. Does anyone know what could be wrong? She went to see a doctor and he gave her medicine, but she's not really getting any better. It happens very often, at least every hour and she said that she was dying, though that's probably an exaggeration. It does sound bad though Do any medics know what she can do and what might have caused this to happen?
