I am b12 deficient, have low folic acid, low iron stores, vit D deficient. I have suspected Postural Orthostatic Tachycardia Syndrome (POTS), celiac disease and an adrenal tumour.
My question is this - I have had low b12 for approx a year and several months ago I recieved my first injection which took my level to 900 but a week or so later it had dropped down to 200, their was no steady decline. Is this normal? What would cause this to drop so fast?
I havent had anymore injections as I have been to ill with the other mentioned conditions and my dr wants to air on the side of caution as my health 'crashed' just after I recieved the injection.
