Narrative:

Unexpected severe turbulence. Seatbelt sign illuminated. Just completed compliance checks. Aircraft began to drop (much like a roller coaster ride) and shake. This was sustained activity for at least 10 mins. Captain tried to find a smooth altitude from FL310-FL290, but moderate turbulence continued until approximately XA25. Aft aircraft inadvertent oxygen mask dropped. Beverage cart (which was in the process of being stowed) let the floor of aircraft several times tossing inserts and contents over several rows. #2 flight attendant sustained whiplash type injuries as did #4 and #1 flight attendants, as well as strained wrists while holding on to passenger arm rests. No passenger injured. Flight attendants continued on 3-DAY trip. Medical advised. Clashing jetstreams probably contributed to the incident. Communication between captain and crew was excellent. Captain reported crew and passenger advised of corrective action he was attempting to take. He also checked on flight attendant's condition several times as we made our way to smoother air. Supplemental information from acn 536390: unexpected turbulence occurred. Cart went airborne, flight attendants hit the floor. I crawled on floor to nearest empty seat to buckle up. Neck and back (maybe whiplash) discomfort occurred. My problem is with the company because they have not yet contacted me to see if I was ok. This is not the first time they have ignored us when we have had problems.
