Cough lasting 2 months
I am 26 nonsmoker. I have had a cough for about 2 months now. I went to hospital last month and he gave me antibiotics because he thought it was bronchitis but they never helped. I went to doctor and he did an x-ray and found spots but put me on antibiotics for pneumonia and told me if dont get better after antibiotics then come back for a ct scan. Im on the third day of antibiotics and still dont feel any different still have the cough and right now my chest feels tight. I am so worried it may be lung cancer. My cough gets worse when I am doing anything physical and my chest will make a rattling sound when I am about to cough up mucus. The mucus is mostly greenish but sometimes white or clear.
