Tingling in the hands and feet are common in normal people.

When this occurs occasionally, it is called a paresthesia (not PN).
It can happen when cold extremities warm up (like when you come in from the snow, and warm up) or from low blood sugar episodes.

When it becomes a constant every day thing all day long, that points to a more serious cause and PN has to be considered. Drugs that are toxic to mitocondria, will damage them and add to the daily assaults that everyone gets from time to time and may push a temporary situation into a permanent one. Abberations in calcium metabolism also cause tingling. Fixing Vit D levels if low, may correct this cause.
Chronic hypothyroidism also causes pins and needle symptoms. This cause tends to last all day long because it is compressive in nature.
