Chronic obstructive pulmonary disease (COPD) refers to a group of diseases with one common feature: airway obstruction. Two major diseases, chronic bronchitis and emphysema, are prominent members of this group. COPD ordinarily features constricted airways clogged with excess mucous (bronchitis) or damaged and deteriorating air sacs (alveoli), which limit the amount of oxygen the lungs are able to deliver to the bloodstream. To top this information off I have  congested heart failure which adds to common symptoms of shortness of breath and cramping legs (which cause doctors to send me for tests to see if I have blood clots.  Since this is a world of specialists and one does not talk to the other, and my GP is not great at communicating with me it leaves me with a lot of research and writing down lots of questions about my condition.
