I feel like I have been swimming under water for too long and my chest burns and feel so much pressure. Since my COPD has progressed I have been having very bloody stools. I have had a scope done to make sure there was not a problem with my colon. I have always had excellent blood pressure but now it has risen about 30 points. I have also had trouble with my heart rate dropping into the low thirties for no apparent reason. Please tell me if these are symptoms from the COPD and if I am retaining too much carbon monoxide is why my lungs feel so full. I am also getting UTI's which I had never had before and I am losing control of my bladder, Please I desperately need answers. I am very confident in my pulmonologist but his bedside manner leaves much to be desired.
