Your image isn't very clear. From what I see it appears the touchpad is cockeyed side to side. The foreground edge is high and the other side is low. Not top to bottom which is what I would have expected.
You'll need to take the touchpad out and inspect it and the frame edge did you properly mount the spring clips (12 screws - 6 per side)?

If you take a good straight edge can you see a bulge in the case just above the touchpad? If you do then you do have a swelled battery ;-{
