Vitamin B12 deficiency is more common than many realize, with the implications of this as well.
This vitamin is an important component for the healthy functioning of the body, as it is necessary for the manufacture of red blood cells. Deficiency signs can develop very slowly, but there are two warning signs that appear on your face, including facial nerve pain and jaundice.
And facial pain or facial nerve pain is a warning sign of low levels of B12 that should be looked for in the face, according to The Thyroid Patient Advocacy.
“Usually, the pain is felt on only one side of the face at a time. This pain varies so much that it will be difficult to describe all the possibilities. It could be a mild pain in the cheekbone just below the eye. It could also be a sharp pain in the forehead.” “Sometimes it goes down from the scalp to the edge of the nose. This may be painful, but it is usually transient.”
A study published in MD Edge Neurology found that vitamin B12 deficiency may cause isolated nerve pain in the face, with reduced touch and pain sensations, as well as numbness on the affected side.
“It was somewhat unexpected that vitamin B12 deficiency would cause isolated facial nerve pain,” said Dr. Gitendra Paroy, a neurologist.
He continued: “Sometimes the treatment of facial nerve pain is very difficult, and patients may often undergo multiple treatment methods without much success.”
A person with a vitamin B12 deficiency often looks pale or has a slight yellowish tinge to the skin, a condition known as jaundice. The reason for this color change is that the production of red blood cells in the body is affected, which leads to a type of anemia called pernicious anemia.
Symptoms of pernicious anemia may include diarrhea, loss of appetite and jaundice.
