Brief Answer:
Nothing to worry about, take treatment as advised

Detailed Answer:
Hello,
I have gone through your question and understand your concerns.
Such localised, short duration tingling may not be of any serious concerns and usually go away on its own with time.
Is there any history of trauma, headache, loss of consciousness, seizures?
Any drugs, diabetes, hypertension, anxiety issues, sleep disturbances?
For treatment you can try amitryptiline for few weeks.
No investigation is required if no above mentioned problems coexist.
Hope you found the answer helpful.
Do get back to me with details for further queries.
Regards
Dr N Kumar
Neurologist
