<s>[INST] i have recently had blood work done for low B12 my levels are at 70. but my iron is fine and i have kidney pain...any ideas? [/INST] Welcome to healthcaremagic, Deficiency is vit B 12 levels is probably because of yourself being vegetarian. you sholud see physician and get treated for the same. Kidney pain has nothing to do with vit B 12 levels and you should get further investigated with ultrasound KUB </s>
