I have a red bump under my eyelid that hurts, is swollen and itches at times what is it and how do i cure it fast?

Chalazion or stye: You may have a gland that is blocked or a stye. Usually stye point in and painful. Chalazion usually painless and point out. If you are bothered see a doctor to fix it.

Very warm compress: As well, use a washcloth, get very warm under water (not hot, as sensitive area). Use as a compress on the swollen area for about 15-20min couple times a day.
