<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing pain in my eye, and its swollen. Ive also noticed pus in my sputum. What is wrong with me?  <response>: You may have trichiasis, which causes the lashes to grow inward towards the eye, leading to irritation, pain, and occasional discharge. Well conduct some tests to confirm it.
