hi, what do you mean by numbness? Is it your feeling of numbness or there is real loss of sensations like touch, pain etc. If you have really lost sensations of touch, pain, warmth, then you need complete work up including CT scan
. But if you can feel touch or pain, and it is just your feeling of numbness then you need not to worry. Sometimes mild normal sensations are perceived as exaggerated if we have a fear of some significant illness like lyme disease
or multiple sclersois or trigeminal neuralgia
in your case. Till you don't have any other symptom you can rest assured. It will resolve spontaneously within few weeks.
best of luck
