Sore tongue and mouth ulcers

Sore tongue is characterized by a swollen and inflamed tongue, and is a symptom of vitamin B12 deficiency that often goes unnoticed. People may dismiss this as a simple irritation or irritation from certain foods. However, a sore tongue can indicate a deficiency, as the body may be struggling to maintain healthy cells in the mouth. Additionally, individuals with vitamin B12 deficiency may develop mouth ulcers or sores, which can make it uncomfortable to eat or talk.
