I have been having some aches & pains across my back between by shoulder blades & wondered if anyone else w/ CF has these types of back aches often.Also, when I cough, my ribs hurt & I wondered why this is so? I thought I had heard somewhere that as time & infections go on, that our lungs become enlarged & wondered if mine are just really close to my ribs now & when I cough they are pushing against my ribs & that's why it hurts. Has anyone else heard this? I know you can't always believe everything you hear, so wondered if anyone else had heard the same thing.
