question: hello i've had a cold for almost three weeks. it started off as a cough and i though it was getting better by week 2 but then came a runny nose & last weekend i was vomitting. This week I have totally lost my appetite, vomit mucus a little, have a hacking cough, cant hear out of one ear,  & cold/hot flashes. Could you please tell me what could be wrong & it i should be examined by a doctor asap?
