does anyone feel like they force themself to cough and bring mucous up.Its like i make myself because i have a pain in my back and i am convincing myself its my lung so its like i am convincing my body its my lung to.But i keep thinking if it was my lung i would have a dreadful cough and wouldnt have to force it up?I do it that much i make the pain in my back hurt more and then i think see it is my lung,its like a vicious circle.xx
