Corneal Scratch? Eye Pain In Mornings

About 2 months ago, my cat scratched my eyeball while we were playing. The doctor said the scratch was "superficial, but long". I used the drops and the cream and did everything I was supposed to and it healed up...for about a week.

Ever since then it "flares up" for lack of a better term. This usually happens when I'm waking up in the morning. Right as I open my eyes, bam! Eye pain. This lasts anywhere from 10 minutes to an hour, but the pain is always the same. It feels like the original injury all over again, but the pain stops much quicker than it did originally.

The last time this happened was at about 4am yesterday (Sunday) morning. I was in the bathroom, holding my eye open for about an hour until I either got too sleepy to do it, or the pain went away. It was hard to tell at that point. Yes, I fell asleep in the bathroom. Since then it has felt vaguely like there is something in my eye, but not enough to make it water or require immediate attention.

It doesn't hurt all the time, just for a day or so after it flares up, and then I forget about it, which is probably the root cause of the flare ups in the first place.

There's no pus, no swelling, no redness until it flares up. My vision is fine as well, even during the flare ups.
