Question
I have had numbness and tingling on the left side of my face near my eye and down to lip area for a year and a half on and off. I have gone to two neurologists and had an mri (w/o contrast in October 2011) that was normal. They say it could be migraine related. All blood work normal. What else could this be?

Hi,

Thanks for posting your query.

These symptoms are suggestive of one of cranial nerves (maxillary branch of trigeminal nerve) and as per you no obvious cause has been detected. The reason for this is not clear to me also.

Additional information like it is continuous or intermittent, do you feel normal sensation to touch, and pin-prick or hot-cold sensation in this area, your blood sugar and nutritional status and any other systemic illness might help me in analysing it further.

Please do answer these queries to help me suggest you better.

Awaiting your response.

Hi,

Thanks for writing back.

In intermittent numbness, your doctor may consider a trial with amitryptaline or carbamazepine.

Please discuss about this with your primary treating doctor.

Hi

As I wrote you earlier, it suggests involvement of one of cranial nerves (maxillary branch of trigeminal nerve). It is usually due to inflammation or demyelination of the nerve. However, exact reason for these cannot be contemplated.
