Hi... Tingling sensation or pin and prick sensation is normally nervous system related issue. It might occur because of many reason like either a recent dental appointment with anesthesia being given or stress, or it might even be an initial sign of a neuraligic pain or even  stroke. Well to rule out the possibility in your case it is very essential that a doctor can examin you. It might not necessarily be some thing very major, sometimes even some kind of food might cause allergic tingling. But no way to assert without a visit
