It s a little complex , cough for 7 months , whooping cough diagnosed, blocked sinuses , chest infection followed, still coughing ...been to docs 2 days ago , more tests to follow to determine if reaction from whooping cough or something else ...and then doc says I also have heart murmur , now worried. I am 45 year old , have cycled all my life, dead on right weight, never smoked. Perhaps a little sleep deprived , stressed and have couple more drinks than ideal....and now quite worried. DOc to listen to heart in 1 month but say not too worried if I can still red up steep hills...which I can, but I also have an awareness of my chest, can feel it, not sure if cough and lung related or heart. Comments welcome
