Radiologist said upper left lung (by 3rd rib) showed haze (they had medical term, but I unfortunately didn t write it down) - this was not the case in 2011 xray . My oxygen levels are good (98). I do not have a cough; however I do have shortness of breath (even when doing nothing, gets more frequent {shortness of breath} when walking up stairs etc.). I do not weeze, and have never had asthma . My white blood count is elevated has been since August. Currently is at 12.94, two weeks ago was at 13.84. I have fatigue . I am 41 years old; have never smoked; however when growing up my father smoked cigerates (one after the other). I have had ekg - good results. Pulmanary test was good. Currently waiting on insurance to approve CT Scan. Have not felt good in months.
