Also, my arms and stuff started to twitch a little when they would go numb.
Hello and hope you are doing well.
Your symptoms of transient difficulty with vision, numbness, lightheadedness could be just a natural occurrence, when people tend to move to different postures fast and quick. 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. So, please have yourself evaluated.
Hope this helped and do keep us posted.
