I know the feeling the exact same thing has happened to me and now it is happening again. I am over it.
Now testing for other things and X-ray. Fingers crossed it shows something
I have these same symptoms. I first got these symptoms 5 years ago, they lasted three months then went away. I got them again last year, I went to the doctor after three months, i waited to see if the coughing went away on it's own again, she told me I had bronchitis and prescribed a steroid. The coughing went away. I have it again, went to the doctor and they told me I did not have bronchitis after looking at chest xrays and it is going on 4 months with no relief. I cough no matter what I eat or drink to the point where my sides and head start to ache.
