Migraines were something Yarraville mum Juanita McLaren and her son son Tibor, 12, had never experienced until two weeks ago.

That's when a West Footscray warehouse containing toxic chemicals was engulfed by flames. The massive fire sent plumes of thick black smoke across the western suburbs.

Since then, Tibor has had four days off school and visited the hospital and Ms McLaren says the pair are not getting any better even if they spend days at a time indoors.

"There’s like a coating in our mouths, and we still have sore throats," she said. "We have stinging eyes and difficulty breathing and persistent coughing."
