Yesterday i felt something pop in my eye and it was sore all day. today i woke up and now my left inside corner of my eyelid is red,swollen,and sore?

See your eye doctor: Go see your ophthalmologist. If you can't get in, see an optometrist. Feeling a popping sensation in your eye is never a good thing, especially when it gets sore. Occasional painfree redness is ok (often due to broken blood vessel) but swollen & sore eye needs to be evaluated. I assume your vision hasn't changed since you didn't comment. Still it's imperative that you get evaluated today.
