Sore Tongue

A sore tongue may be a sign of nutrient deficiency, often iron, or vitamins B6, B3 or B12 — or all of these. It is a good idea to have a blood test to get your iron levels measured, and to take a strong vitamin B complex with perhaps a vitamin B12 injection for added effect.

Other causes of a sore tongue include dental trauma, candidiasis, food allergies, oral ulcers, lichen planus, salivary disorders, metabolic disorders, hormonal imbalances, chemical or drug toxicities, kidney disease, drug sensitivities, and collagen vascular disorder.
