Phone turns on, but won't let me click anything like messages etc.

Hello, my blackberry bold 9700 is having problems. Last night I had my phone next to me, next thing i know i heard the camera taking photos I picked it up and it would not let me get out of the camera so i took the battery out a number of times and also my sim card and I turned it back on.

Then I can not click on anything my touch button in the midle of my phone that makes me click on things will not click - it moves from left to right but wenI go to click on anything it will not let me. This first happened wen I received a text and I went to look at it and it did not let me.

Also it wont let me type anything on the keypad at all. Numbers no button is working apart from the touch bit in the middle it does not let me turn my phone of or lock it. It is turning on as normal, like it has ever since I got it, because I can not click on anythnig when it goes blank it just turns off and I need to take the battery out and put it back in to turn it on.

I had my phone in my pocket when it was raining last night could this have damged it? Is there anything i could do instead of taking it into a technician?
