Hello
I have COPD and on Oxygen for activity In 2016 September 12th I had a left lung lobectomy bottom half removed , because of two cancers on lung, operation was successful, recovered from that, i also have fibrosis and emphysema , my activity levels are very low now , not exactly young no more either 62 years young, anyway I get so damm tired now mid afternoon just exhausted to be honest , is it because of my lungs in such bad health are causing this extreme tiredness.?
Thanks
