My mother had borderline normal b 12 levels. She is having few issues in her legs like when she wakes up her toes tingle and she isn't immediately able to keep her legs on floor. She is also iron deficient. She sometimes have breathlessness when she talks a lot. And cannot stand for long period of time. Her legs feel weak. We have already consulted multiple doctors face to face but all of them say it's
thyroid all though her
tsh is is normal range now. She has been on acidity controlling pills and birth control since 5 years. Can b 12 deficiency cause these problems if yes than she take pills for it
