Hi, I think I've run out of ideas and the doctors that we've seen do not seem to know what might be the problem with my dad. My dad cannot breath easily and he has chest pains and has to press his collar bone so that he can breath easier. He is 64 and retired, has never smoked, nor does he drink, and he is underweight. There is no coughing involved when he can't breath, its a constant but he does get 'attacks' sometime where he is gasping for air. We've tried inhalers and the lot and nothing seems to help him. Can someone suggest what might be wrong with him? We've ruled out GERD, COPD, Panic Attacks...
