What Causes Creases On The Eyelids?

Hello I ve had a problem for a while now that I ve been wanting to address. Around 5 or 6 months ago I awoke to find my right eyelid had several more creases that the left. I ignored it and thought it would go away. A little while ago I saw that my left had gotten some too. Now my right eyelid has 3 or 4 creases and my left has 2. It is very uncomfortable. I can t look up without feeling a little pain and when I look strait it seems as my eye is half closed. I ve tried things to fix it at home. Hot towel soak, cold towel soak, putting ice on it, steaming my face, everything hasn t worked. The reason I m asking the question now is in 18 days I m going to a costume convention and I ll be having professional photos taken. And I don t want my eye make up to be lopsided. So I was wondering if there is anything I m missing and would really love if you could help with figuring out what to do. Thanks for listening.
