Clicking/knocking sound from crank area

We've recently purchased a trainer and lately I've noticed when I'm riding on it I can feel and hear sort of a clicking or knocking sound from the crank area. I can actually feel it on either pedal while riding so I'm starting to think it's something with my front sprocket, or between the cranks. I ride a 24-speed road bike. It's slightly better when I'm in the highest gears peddling faster but it's fairly constant in 21 or 22 gear.

Now that the ice has melted outside, I got out and rode yesterday, and I couldn't feel or hear any trace of it. Any idea what may be the cause of this? I wish I could just ignore it but I'd hate to get stuck 20 miles from home because I didn't get something fixed.
