low fever and caught

Good day,

Four weeks ago my doctor told me that I have bronchitis (which I have as chronic disease which, from time to time become acute) and she gave me HIRAMICIN which is semi synthetic tetracycline antibiotic and I take it for 10 days, however even after all caps taken, I still have cough, runny nose and last few days again I got low fever such as 35 degree Celsius (95 Fahrenheit). I have also chronic laryngipharyngitis which wakes up from time to time. Some time I feel also scratching throat. Caught usually start when the temperature in surrounding change. To be complete information, I smoke more or less 20 cigarettes a day and I have kitten in house, Each day I'm also in contact with wooden and coal ash from our fire place used to heat house. (sorry for my non perfect English)

Thank You
