The vitamin deficiency that causes tongue tingling is folate, vitamin B-9 and vitamin B-12 which can also make your tongue swollen, sore and affect your sense of taste and even cause tingling sensations in your feet and hands.
Paresthesia of the tongue is an unpleasant sensation of tingling or prickling or a feeling of burning or swelling of the tongue with spontaneous onset.
The paresthesia of the tongue can be a result of idiopathic causes, psychogenic causes, systemic causes or local causes.
Tingling in the tongue or parasthesia of the tongue can happen for many reasons, including nerve damage, an allergic reaction, a stroke, and low blood sugar.
A tingling tongue may also indicate a canker sore is forming.
Oral paresthesia or tongue paresthesia may be caused by manipulation or inflammation of a nerve or tissues around a nerve, direct damage to a nerve or tissues around a nerve, tumor impinging on or invading a nerve, primary neural tumor, and central nervous system disorder or tumor.
If a deficiency in blood sugar or calcium is the cause of paresthesia, this tingling sensation does not occur until your calcium or blood sugar levels are severely low.
It's essential to note that tingling and numbness in the tongue, lips, or cheeks are some of the more severe signs of low blood sugar.
The duration of tongue paresthesia is unpredictable.
Tongue paresthesia may last days, weeks, or months, or in rare cases, it may be permanent.
Treatment for tongue paresthesia will depend on what is causing your tongue paresthesia.
You may need to increase the amount of vitamin B in your blood.
Your doctor may change or stop a medicine you are taking that is causing your symptoms.
Permanent tongue or oral paresthesia may be helped with nerve medicine.
