Slicing Up Eyeballs

My eyeballs have been having some problems. First, the last few days I was in Fukuoka, my right eyeball was aching and I woke up the last morning I was there to a red, swollen eyelid. Some kind of infection. I've been taking some anti-biotics and its clearing up, though it's still red and achy. Then yesterday, my left contact was stinging all day, and in the evening when I took it off, my vision was all cloudy. I looked in the mirror and it looked like a piece of dust was on my cornea, but it wouldn't wash off. So I called Dad who said it might be a corneal infection and I need to see a doctor right away. I checked out clinics in Sendai online and went to sleep with my eyeball still stinging. Then when I woke up, it had cleared up. I guess it was just something stuck to my eye after all - and at least I can see again. I guess it's time to start a new set of contacts.
