[|Human|] My daughter was having back pain for a while. Now she has some nub ness in her left hand but mostly left foot. She does nos not have full range of motion in her ankle and it is hard for her to move her foot In an upward motion. She has a bad diet and does not take vitamins. Could she has b12 deficiency?
[|AI|]  Yes, chronic back pain, nub less in her left hand, left foot and decrease range of motion at ankle might be due to vitamin b12 deficiency. But If I were your treating Doctor for this case I would suggest serum uric acid, fasting blood sugar and vitamin d3 level investigation along with it b12. Hope this answers your question.
