I recently posted to a forum user about
Wolfe-Parkinson-White Syndrome. If she is in her late teen years, it might be worth checking out. We had so many issues with our daughter. Then, the doctors' appt. would have 0 results. We used to leave feeling cheated emotionally, physically and financially.
One day after she graduated, she was right in front of her college and passed out behind the wheel. Finally, it took an ER doctor to diagnose her condition.
