The weird feeling in the tongue, often described as tingling, numbness, burning, or a pins-and-needles sensation, can be caused by various factors. Common causes include allergic reactions, vitamin deficiencies (especially B12, iron, or folate), anxiety and stress, nerve damage, oral health issues like canker sores or infections, medication side effects, and low blood sugar. Tongue trauma from biting or burning can also cause discomfort. In some cases, this sensation may be linked to more serious conditions like multiple sclerosis or stroke, so persistent or severe symptoms should be evaluated by a healthcare professional. Managing anxiety, avoiding allergens, addressing nutritional deficiencies, or treating infections may help relieve the sensation.
