Hey, I have had a cough for 2 months now. Was treated for Allergies with Flonase, zirtec and teslone pearls, that did not work. Then I was treated for Bronchitis with doxycycline, steroids, hydrocodone syrup and singulair. I have also had a Z-pak and nothing is helping. I have a dry nagging cough and it is very consistant. Doctor suggested I come in for x-ray and I wanted to know if it was something that I should do because it will be expensive without insurance. That would make the 3rd time going to the doctor
