Narrative:

Approximately 25-30 mins prior to landing in phl; flight attendant #2 and I were in the aft galley when we were first suspended in the air and then thrown to the galley floor due to what the captain later told us had been the wake from another aircraft. Flight attendant #2 bruised her back from above her hip to her shoulder blade on the corner of #4 jumpseat as she was forced down by the g-forces. I had been standing next to flight attendant #2 in the galley; but was closer to the door when I was forced down by the g-forces. I only had a galley wall behind me -- nothing protruding; so I did not bruise my back. Flight attendant #2 called the cockpit to inform them of her injury and to inquire as to what caused the turbulence. The captain told her that it had been wake from another aircraft. Flight attendant #2 told the captain that she was bruised; but did not need any immediate medical attention.
