Could it be my heart?
For the past few years I have had increasing fatigue. I am a 57 year old female who works a stressful nursing job full time. I have mild sleep apnea, and use CPAP, but that has not helped with the fatigue. I have anemia and my ferritin level got down to 5. No source of the anemia has been found. I take daily ferrous gluconate. I also take 2000 mg of vitamin D every day, as well as sublingual B-12 and a multi vitamin. I fall asleep in movies, meetings, and can only drive for 30-60 minutes before getting drowsy. I have had 3 episodes in the past few years where I became very weak, nauseated, diaphoretic, for no apparent reason. My blood pressure runs normal to low. I have never smoked, but grew up in heavy 2nd hand smoke. The one odd thing that makes no sense is that sometimes I get a sensation like there is air rushing through my heart. I am afraid to open a bag of worms by drawing attention to this in a doctor appointment. Any thoughts? Yes, nurses go through denial :-)
