Has anyone experienced low blood pressure and hair loss coinciding with other symptoms? If I have a good few days (rare) when my fatigue is lessened my hair loss slows down and my blood pressure climbs back to my post-illness range (110-120 systolic). If I'm really sick my hair loss is at its worst and my blood pressure won't climb up beyond 85-95 systolic. All labs and hormones (including thyroid) checked out normal multiple times. The only thing out of range for me is my vitamin B12 that is a little high and my BUN/CREATINE is a little high. Doctors did not pay any mind to any of these references in the past. They said high B12 happens and is not dangerous. I wasn't taking any vitamin or B12 rich supplements at the time of my labs last year. How does CFS relate to blood pressure and hair loss? How can it be possible for these symptoms to change on a dime so quickly from one day to the next?
