Yesterday i took a nap and woke up with a bump on my eyelid to the point i couldn't open it all the way. I thought maybe something bit me or idk but it went away like an hour later. today around the same time as yesterday i noticed a tiny bump on the same spot and it kept growing to as big as it was yesterday, it took about an hour maybe a little longer to form. and it went away maybe two hours later. Is this something i should be worried about?
