Slipped disk?

Yesterday I slipped my disk at 33 weeks pregnant. It was an injury prior to being pregnant but my back gave out yesterday. I can't even lift my leg. Has anyone else suffered a slipped disk during pregnancy?

Also since I slipped it yesterday my appetite has increased. Weridly. Every hour I am hungry again. To the point where my stomach is rumberling. In the last 24 hours I have eaten so much. All healthy food too. This whole pregnancy I can go the whole day on three meals or even two but since yesterday it's hourly.
