'98 zx2 5 speed tranny issues

When i put my car in reverse tonight it got stuck in gear. I could not get it out of reverse. Rocking the car back and forth with the clutch in did not help. After 5 minutes of trying it finally got out of reverse. However, when i started to go down the road it would not go in 2nd or 4th. When i got home i tried and it would not go in reverse as well. All i have is 1st, 3rd and 5th. Anyone have an idea what could be wrong?
