Hi, your symptoms of transient tingling could be just a
natural occurrence, when people tend to be in a
particular position for long
. But it could also be due to an entity called TIA or transient ischemic attack, which as the name indicates there is a temporary lack of blood flow to a particular part of the brain. This usually recovers, but these people are more prone for strokes. And anxiety can cause high blood pressure. So, if your symptoms persist, please have yourself evaluated. Regards.
