No-one wants to see you turn your and cough... Seriously, if whatever it is is bad enough to warrant asking for a doctor, go see a doctor... Failing that, insert the general GP spiel of 'eat less, cut down the drink, stop smoking, exercise... take some ibuprofen and call me in the morning...' And if it's an irritating arsehole that's nagging at you... tough luck, you're stuck with Trump...
