Houston sat out of Monday's Detroit Lions practice because of a migraine headache, something he said he's dealt with since he was young.
"Sometimes if I eat at a certain time or sometimes they come at the middle of the night," Houston said. "It's just hard to pinpoint."
He says it's a hereditary trait in his family.
"My mother goes through it and my sister goes through it and my auntie," he said. "It's hereditary on my mothers side, so I suffer with them from time-to-time."
He is prescribed the medicine Imitrex and says the headaches usually subside about an hour after he takes it. Houston has had them on game days before, but has been able to get to his medicine in time for them to stop by kickoff.
"The quicker I get to my medicine the quicker it goes away," he said.
Former Minnesota Vikings and current Seattle Seahawks receiver Percy Harvin has had a well-documented history with migraines, but Houston said he's never talked with him about it and doesn't know the severity of Harvin's compared to his own.
Houston signed a five-year, $25 million contract this offseason after solidifying his status as the team's No. 1 cornerback last season.
A migraine has never kept him out of a game, but it's something he has to deal with from time-to-time.
