咳嗽很久，吃了很多抗生素。

I have coughs many times since last year. I feel itch first at my throat. then i coughed for several weeks. it is horrible experience and everytime after visiting dr. I got the 抗生素 and 激素，I don't want to take any 抗生素 and 激素 more. I feel very weak. After visiting a US dr. he told me not take anything and many ppl have the same problem. However, there is no improvement in my cough.

How could I do? visit dr again and get 抗生素 and 激素，I already took more than 200 pills of 抗生素 for the past year.

I have never been so sick. Been in US for 10 years and never got sick.
