My eyes are so sensitive to light, and hurt at the top!?

Sounds like you could have pink eye or any form of infection or inflammation that would case sensitivity to light. Without seeing you it is hard to tell if it is just simple pink eye or you have a more serious problem like iritis/uveitis or corneal ulcer. If it is that painful you should definitely see a doctor to get treatment as leaving it may result in permanent damage. Please try and stay out of your contacts until you see the doctor. All people who wear contacts should have a pair of gles as back up for accasions just like this.
