ASHBURN, Va. -- A 26-year-old cheerleader in Virginia claims she came down with a rare neurological disorder just days after receiving a flu shot.

Desiree Jennings, a Washington Redskins ambassador, says her problems began ten days after receiving the seasonal flu shot at a grocery store. She claims she fell ill with flu-like symptoms and then experienced convulsions and blackouts.

Inside Edition showed video of Jennings, an avid runner, struggling to walk forward and speak properly. When attempting to walk forward, Jennings appeared to jerk around and have difficulty moving. However, she could walk backwards and run without any problems. Also, while running, Jennings could speak clearly.

Jennings says after seeing dozens of doctors, she was diagnosed with Dystonia -- a rare and debilitating neurological dsorder that affects muscular control. The condition, with no known cure, is usually caused by head trauma, drug use and poisoning.

According to Jennings, medical hospitals ruled out everything after all her tests came back normal. The only explanation, she says, is that the shot caused her condition.

The FDA reportedly found nothing wrong with the batch of influenza vaccine given to Jennigs.

Prior to getting the shot in August, Jennings was training for a half marathon. She says she received the flu shot in 2007 and 2008 without any problems. Her case is apparently a one-in-a-million occurrence.
