My story is actually a pretty sad example of the health industry:
I went in to the workers comp clinic because I was having terrible back pain and I figured I did it at work (I am a professional tradesman). well the doctor asked me to breathe in deeply, and I tried, but told him that it hurt too much. He basically dismissed any of my complaints about how it was hard to breathe, and that only one side of my back hurt. He basically just wrote me a prescription for pain killers. (which I never took, because I don't like how Vicodin makes me feel. So I sold them to a crack head at work)
Well, the pain got worse, and I also started to have a fever. I went back to the same clinic, and this time I got a different doctor ( younger and maybe a little more patient) and diagnosed it as Pneumonia!!! My entire left lung was fully filled with fluid!!! WTF!!
So I did several rounds of antibiotics, several cat scans, was assigned a pulmonary specialist and one draining. Yeah, that draining was the worst part! They poked into my lung with the longest syringe I have ever seen. That was an odd feeling when I could actually feel the fluid draining out of my lungs. It felt like I have coughed up the biggest phlegm ball! I also lost 25 pounds of weight. I looked like a skeleton!
I hope I never have to do that again. The bad part is that the doctor told me that when you get Pneumonia, it leaves a scar in the lungs that makes it easier for you to get it again!!!
