Hi,
Left-sided
tongue numbness can suggest a variety of conditions, including nerve damage, inflammation, or a lack of blood supply to the area. In your case, your
neurologist has ruled out any major neurological issues based on your CT scan, which is a good sign.
Your osteopath's assessment that your symptoms may be related to cervical and temporomandibular joint (TMJ) dysfunction is a plausible explanation. TMJ dysfunction can cause
referred pain and numbness in the face and fingers due to the complex network of nerves that supply these areas.
It is also possible that your symptoms may be related to other underlying conditions such as a
vitamin B12 deficiency,
autoimmune disorders, or side effects of certain medications. However, your healthcare provider(s) should be able to help you determine the root cause of your symptoms through a comprehensive evaluation and additional tests if necessary.
It is important to follow up with your healthcare provider(s) to ensure that your symptoms are properly diagnosed and treated.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
