Hello, approx. one week ago my son had symptoms of dizziness, nausia, and felt like pins and needles while driving home. he had to pull over and park in a restaurant lot and we picked him up. we thought it might be due to a busy day combined with too much caffeine and he was feeling better the next day. This evening he stated that he was feeling like he did a week ago. He was out all day but not cause for feeling the way he does.
