Night terrors...

My 2 year old has never been a good sleeper. She's been having night terrors every now and then nothing constant for the past few months. The past week or so they've gotten a lot worse! Last night she had 3! My husband woke her up the last time and she was so scared to go back to sleep. Anybody else dealing with this? Anybody have any suggestions on how to help her? We're going to the doctor in Monday I just figured I'd ask here before we go.
