I know this topic has been discussed many times. I am also in a dysautonomia group and to confirm my own suspicions they think i have it. Aside from my heart murmur, i have nearly all the symptoms ranging from dizziness/balance probs to fatigue and muscle probs to anxiety and heat intolerance. SO ....as i also wonder about lyme disease...is CFS and or fibro a misdiagnosis of dysautonomia????? How many have heart murmurs?
