Hello I am 57, 53 when I first went to the hospital because it was hard to breathe. Also I have had a murmied heart, (nosiey heart), since birth. I have PH, PPH, and CHF. Do to my "off the scale" Pulmonary Hypertension, it has put me into congressive heart failure, CHF. The symptoms you are having is many of which is connected to Pulmonary Hypertension. PH slowly robs your body tissue of oxygen making is hard to breathe, sleep, rapid heart beating, lower stomage and back pains, and always ending your life early. There is no cure. I truely hope you do not have this! I've been given two to five years, over three years ago. Leaving behind my wife of nearly forty years, and five children. PEACE As for the pale skin; you need sun.
