Sounds horrible! Some kind of viral infection I guess. I had bronchial pneumonia years ago and I felt kind of like that. I felt like I had been run over by a train, coughing up blood. It took me a while to get over it but not six months.
Nope, no blood with me, and it wasn't pneumonia, although from what I have read it's similar. It was some bug that come up over the border. The doctor said it's because they have access to antibiotics but never take a full coarse and so the bugs get stronger and stronger. I coughed so much that my diaphrame got so tired it would hardly work.
I let it go too long because I was so strong and was not used to getting sick so I didn't realize how bad it was until it was almost too late.
