copd is another name for emphysema and it is not caused by a fall. there are many lung disorders that can mimic copd so you may want to consider getting a second opinion from a pulmonologist (lung specialist). you are having several other symptoms that are not typical of copd so it would be prudent to have another professional render an opinion as to the cause of your problems.
can you get copd from a fall. fell off a scaffold a year ago around 5 ft high. tore my both shoulders and herniated a disc in my back t3 t4. i have had trouble breathing since. tightness in my chest and sore throat. feels like there is something in my throat. i also have pains up my neck into my head. was told it was copd. i can walk without any trouble and have trouble sleeping.
