Narrative:

At approximately 18000 ft (after takeoff) during climb out, our aircraft experienced sudden and abrupt turbulence. After 2ND chime, I waited to get out of my jump seat, due to our steep attitude. It occurred 15 mins after takeoff, as I was setting up my beverage cart at the row 2L/2R galley area. I did not pull the cart out, I only began to prepare. The aircraft took a sudden drop/descent and I was forced to the floor and landed on my behind. My elbow and shoulder hit the bulkhead at row 2L. I crawled to situation in the xc seat which was unoccupied. I buckled the seat belt and remained seated in xc until the cabin stopped bouncing around. The captain phoned back, using the interphone and told us to remain seated and to find out if we were hurt. I was totally unaware that there was severe WX in the area. I was totally unaware that we would be going in and or around thunderstorms. Information was inadvertently kept from the cabin crew, or was not made aware to me. I would have remained strapped in my jump seat, as I do if informed prior to departure, of any expected turbulence in and around the area.
