My sister had to be ambulanced 3 times to hospital in a week due to breathing trouble so bad she thought she was going to die. She was also hardly managing to even walk far due to the trouble breathing she was having. This all had come on quite suddenly.
The doctors at the hospital kept on just sending her home and rang her partner at work and told him they thought it was depression!!! (and anxiety).
On the third occassion of the ambulance having to be called as she wasnt able to get enough air... they finally had her blow into one of those things and realised her "peak flow"? was quite low. At this point they sent her home with a nebulizer which she was using almost constantly. It didnt seem to do much for her.
Later that day she had a coughing fit and coughed up what was a filling. At this point her breathing issue disappeared and it hasnt come back
We believe she must of had the filling from the tooth lodge in her lungs (she had soreness in one of her lungs).
