Hi..
Can understand your concern..
As per your complain Unilateral
numbness of face and ear can occur due to the infections or injury to the
Trigeminal nerve and its branches that supplies different areas of face as trigeminal nerve is the nerve of face..
Any injury like trauma due to dental treatment and injections, direct injury due to any accident, infections (
encephalitis), tumour and cyst compressing over the nerve can lead to disruption in the activity of the nerve and can lead to numbness..
While the numbness of face can also occur as a result of some other conditions like
Stroke, ischemic attacks, multiple
sclerosis, etc..
I would suggest you to consult a Neurophysician and get evaluated..
He can advise you an MRI done and a single exposure does not lead to cancer as well as MRI is a correct diagnostic tool towards diagnosis in your case.
A proper diagnosis is a must for a proper treatment plan..
As of now start taking zinc and Vitamin B complex supplements..
Hope this information helps..
Thanks and regards..
