Numbness on right side of my cheek some twitching no other symptoms elsewhere what could it be?

Get checked: Numbness is a symptom that always requires medical attention. First I would check to make sure that your facical nerve is patent with no impingment. Twitching has many causes., some of which are not a big concern. Among the big concerns would the issue of Lyme Disease.

Uncertain: It could be a benign transient phenomenon or, if it persists or recurs, there might be some underlying cause. For persistence or recurrence, one should see their doctor or a neurologist.
