More Info

---

Tongue numbness can be a concerning symptom, and it is important to understand the potential causes and implications of this condition. Based on your description, it seems that you are experiencing numbness in your tongue, along with the presence of red spots on the sides when you curl your tongue. This could indicate several underlying issues, and I will outline some possible causes and considerations.

1. Inflammation or Infection: The red spots you observe on the sides of your tongue could be indicative of inflammation, which may be due to various factors such as infections (viral, bacterial, or fungal) or irritations from certain foods, medications, or oral hygiene products. Conditions like glossitis, which is inflammation of the tongue, can lead to changes in color and texture, and may also cause numbness or tingling sensations.

2. Nutritional Deficiencies: Deficiencies in certain vitamins, particularly B vitamins (such as B12, B1, and B2), can lead to neurological symptoms, including numbness and tingling in various parts of the body, including the tongue. A lack of iron can also contribute to glossitis and other oral health issues. It may be beneficial to evaluate your dietary intake and consider supplementation if necessary.

3. Neurological Issues: Since you mentioned that you have previously experienced numbness in your hands and feet, it is essential to consider neurological causes. Conditions such as multiple sclerosis, peripheral neuropathy, or even transient ischemic attacks (TIAs) can manifest with numbness in various body parts, including the tongue. If your neurologist has suggested that there may be a neurological component, further evaluation may be warranted.

4. Allergic Reactions: Allergies to certain foods, medications, or dental materials can cause localized swelling and numbness in the tongue. If you have recently introduced new foods or medications into your routine, consider whether these could be contributing to your symptoms.

5. Anxiety and Stress: Psychological factors can also play a role in physical symptoms. Anxiety can lead to hyperventilation, which may cause tingling or numbness in various body parts, including the tongue. If you are experiencing significant stress or anxiety, addressing these issues may help alleviate your symptoms.

6. Other Medical Conditions: Conditions such as diabetes, thyroid disorders, or autoimmune diseases can also lead to neurological symptoms. It may be worth discussing these possibilities with your healthcare provider, especially if you have other symptoms or risk factors.

Given your history of neurological symptoms and the current issue with your tongue, it is advisable to follow up with your neurologist or a healthcare provider who specializes in oral health. They may recommend further diagnostic tests, such as blood tests to check for vitamin deficiencies or imaging studies to evaluate for any neurological concerns.

In summary, tongue numbness can arise from various causes, including inflammation, nutritional deficiencies, neurological issues, allergic reactions, and psychological factors. It is crucial to consider these possibilities and seek appropriate medical evaluation to determine the underlying cause and receive appropriate treatment. If your symptoms persist or worsen, do not hesitate to reach out to your healthcare provider for further assistance.
