Oh the fatigue !! Finally not totally consuming. No aerobic exercise has helped a lot. Very short dog walks only.. I too have had every test . Some blood work necessitated taking supplements that I never took before! I completely surrendered to the LC beast and it really helped me!!! If I am tired I lie down . As soon as I feel that chest tightness and body crumbling I lie down ! My friends ask where I have gone as I was always so active. I never listened to or respected my body as much as I do now and it helps. Listen to your body and that will help! Arthritis has been going gangbusters tremors sharp pains in hands and feet !! So many symptoms. No wonder doctors are so confounded by this beast! At least I truly believe we are finally at least being believed .
