My local brother is in Jackson, MS, this week undergoing a second battery of tests, this time under the supervision of an infectious disease specialist.

He has been feeling poorly since March, when he suffered what he thought was a bout of flu. For nearly three months now, he's suffered from headaches and intermittent fevers, along with a debilitating lack of energy.

Doctors have been successful at ruling things out, but they can't get a grip on what ails him.
