Hi , I am new to this page. I have suffered with COPD for 5 yrs or so. I have a reaccuring pain in my left lung. A stabbing pain when I move or breathe in . I was looking on the net to find out what it could be and found this page . I think It might be plurecy and I have had this a numerous times over the years,but I have never been diagnosed by the dr with it !
