Open Question: My right eye hurts. It is swollen and itches from time to time?

Yesterday I woke up and my right eye felt quite sore like I had a bruise inside my eyelid. It hurts slightly every time I blink or close my eyes and itches from time to time. Today I looked in the mirror and it's a bit swollen on the upper inside eyelid and the skin is a bit pink. The pain is mostly coming from the outer side of my eye like someone is jabbing my eye every time I blink. Please help. Should I go to the doctor?
