I recently flew a long haul flight and went straight back to work he next day, so I've been a little tired. A few days ago, though, my eyes started itching and they are now red. I keep getting lots of sleep, but still feel tired. I thought it might just be a cold, but last night my eye suddenly started buring in pain. Whe I was checking to see if aything had gotten into it I noticed that it was a little pale yellow under the lower eyelid. The right eye is worse than the left, but both had this. As far as I can tell it is ot raised but I have been itching my eyes a lot. It wasn't red before it went yellow though. I'm sure it's something relatively new since I've never noticed it before. I have a serious phobia bout my eyes so would really like to avoid seeing a doctor. Should I be concerned.
