I have all the symptoms of emphysema and chronic bronchitis; chest tightness and back pain, coughing blood, shortness of breath when I exercise, and always tired. Overinflated lungs is all that shows on x-ray but I cannot get diagnosed with anything, and cannot get the right medication. My symptoms get worse when I go the city with the smog and near the ocean and gas heaters and cooking smells. So as you can imagine, everyone tells me it is in my head; definitely not. I have been perfectly fine up until 4 years ago when all this started. I don't know where to turn to next. I had bronchoscopy, CT chest scan, MRI of back (for the pain); my symptoms just are not getting better. I have seen 3 respiratory doctors and all say there is no cure, I cannot work out what's happening. [removed by moderator]
