Rosie Perez On Her Shaken Baby Syndrome

Actress and AIDS activist Rosie Perez claims she was injured back in Sept. 2009 on the set of "Law & Order: Special Victims Unit." Now, ET talks to the Emmy-nominated actress to find out why she is wearing a neck brace and why she was scared for her career.

"I have two slipped discs, one bulge, three sprained ligaments, and a pinched nerve, which resulted in minor nerve damage," Rosie tells ET.

She says the problem began during a stunt, which she says resulted in shaken baby syndrome, but she says she was initially misdiagnosed, and, as a result, she waited a long time to get a correct diagnosis.
