Hi there, thanks for asking. It is a good question. Although migraine
which is classis does not need so much investigation, migraines which are with focal signs like the pins and needles that you mentioned need full examination to see if there is any underlying issue which should be addressed. If it is repeated in the near future in the same pattern, it should definitely be investigated. At this time, you should not worry and wait for the next probable attack to see how it is. I wish you a good health.
