How can you relieve a pimple in your lower eyelid?:(?

I have a pimple in my lower eyelid. It's small, but it hurts a lot. Everytime I blink it hurts. It's like a burning sensation. I've tried putting a wet cloth in my eye for these past 2 days, but it hasn't taken away the pain. It's my first time I've had this. I'm not sure if it's a chalazion because I've had a chalazion before. The weird thing is that I have like a pimple in my other eye, but this one doesn't hurt. I'm thinking that it might be a chalazion. Can you please give me some advice in how to remove my pimple and possible also a chalazion. Thanks!!!!!!!!!! :)
