The left side of my iPod is white after I dropped it

I had it charging on the table. I went to set it down but I didn't put it all the way on the table. The charger pulled it down and it fell to the ground. It didn't crack and it was fine. I thought nothing of it but I didn't turn it on to fully check. An hour or two later, I go to use it and some of the left side of the screen is completely white. I can use it fine. I can touch it and it works. But I'm noticing that the whiteness is getting bigger. Is there a way to fix this?
