I have a bump inside my eyelid?

I have a bump inside my eyelid. I don't think it's stye because its not itchy and It doesn't hurt, it's just there. I've had it for a little over a year. My mom said it may be grease but I don't know. I haven't gotten to get it checked because I don't know where to go. Is there any way to pop it or is it something serious? Oh and I'm 14

dont pop it..it might be a stye any doctor probably tell u what iy is . ask youre mom to call and make you a appointment
