Kenya Robinson said the shooting happened after she dropped off customers early Saturday in the city's Back of the Yards neighborhood.
She said a car with its lights off started following her near 50th Street and Damen Avenue, and someone inside started shooting.
Robinson is out of the hospital but said she's in a lot of pain. She was driving to make some extra money to move out of Chicago.
She said police think the shooting may be a case of mistaken identity.
She has started a GoFundMe for medical and moving expenses.
