Thank you for posting your query.
Numbness of face denotes involvement of the Trigeminal nerve
, that emerges from brainstem
area of the brain.
At age 30, demyelinating illnesses such as multiple sclerosis
is more common. Stroke as you suggested is uncommon at this age.
Numbness can also be due to mechanical pressure over the nerves of skin over the affected area.
For confirmation of diagnosis, you would need an MRI scan of the brain.
Please consult a neurologist
for detailed evaluation.
Wishing you good health,
