I've had fatigue of unknown origin for years, mood swings (not depression but more easily frustrated kind of thing), inability to lose weight, hair loss, dry skin
, digestive issues. I've also developed eye issues, excessive tearing and
irritation. I have eye drops from the eye doc that help, but the issue flares up.
My b12 was hovering around 200, which by western standards isn't deficient, but with symptoms my PCP decided to treat with injections.
