Last week, a plane had to make an emergency landing after LIL WAYNE started experiencing some sort of seizure-like symptoms. (--His people say it was just a migraine...others say it WAS a seizure.)

Regardless, Wayne's doctors have ordered him NOT to fly.

Wayne had been at his mother's house in Louisiana all last weekend...but he returned home to Miami in time to attend Tuesday's Miami Heat game. Supposedly, he made the trip by BUS. (--There are no other details on his situation.)
