### Patient: I have been experiencing headache, sleepiness, and lacrimation lately. Also, there is sometimes pain in my eye and I have trouble breathing at night. What could be the cause?
### Doctor: Based on your symptoms, it sounds like you may have pinguecula, which is a growth on the white part of the eye that can cause redness, irritation, and dryness. It can also cause apnea or sleep apnea, which is a condition in which you stop breathing during sleep.
