Android G2 touchscreen is left-right reversed

The touch screen on my Android G2 is suddenly reversed. I touch an icon on one side of the screen and an icon on the opposite side is selected. I slide to pick up the phone and instead the sound is turned off. I scoured the web for an answer but all I found was this question. http://community.htc.com/na/htc-forums/android/f/99/p/8610/37534.aspx#37534 Anyone know how to fix this?
