My lungs hurt and I feel terrible (fatigued & sick) when I wake up each day, after having moved to a new apartment in a new city. I feel okay once I get outside and exercise for a few hours. Could it be mold or allergens or CO or what? I am 41, 5'9", and seem to have a very sensitive system. Used to get colds and bronchitis a lot. Smoked for 10 years, but haven't smoked for last 15 years. Am extremely health conscious nowadays, in order to deal with arthritis and multiple physical injuries.
