Burning sensation in the head. Next?

Hi I have got cold and upper respiratory tract infection, after two rounds of antibiotics it is still persistent and not going. Cough, runny nose, irritation in throat and chest with repeated cough & post nasal drip was my complaints a month back. Visited ENT and got a weak medication of montec and augmented 625 course. Runny nose subsided a bit but I had cough and wheezing problem. I was referred to pulmonologist and he gave me another round of antibiotics and montec for a week. That also didn't work. After chest x-ray and pft test in the Next visit he has given nasal spray and puff with spacer. Cough has come down but burning eyes, pressure in head and burning sensation in the head accompanied by irritability with thick nose discharge started. I have started Azax 500 today with montec.. still not feeling any better. What should I be doing next?
