Does Caffeine cause Anxiety?

Hey I was reading a little and said that caffeine can give you anxiety. I notice when Im in big groups of people, I tend to get sweaty hands when i dont feel nervous. I do get nervous once my hands begin to sweat however. I give lots of handshakes with people and its very embaressing. Should I stop drinking soda with caffeine. What should I do need help ASAP.
