I bet all of us can say (at some point in our life) that we have awakened in the morning, looked in the mirror and found a red lump on our eyelid. Eeewww!!! Where did that come from? This is an acute infection of an eyelash follicle in the eyelid margin. What to do? Warm compresses up to four times a day and wait for it to clear up. If it worsens, you may have a chalazion going on there and you should schedule to come in to see us.
