I have inflammation in the corner of my left eye on my skin size of a pea, red and raised, swollen. it doesn't hurt just appeared a few months ago.

See eye doc: It may be a blocked oil gland called a chalazion. Use a warm moist compress on it for 15 minutes 4 times a day until you see your eye doc who may have to drain it.

Excise: A new raised bump on eyelid skin, which persists, can be malignant, tho unlikely. It should be seen & biopsied or excised. This is usually done in the exam chair & takes a few minutes. Worth pursuing.
