Suggest Treatment For Stye In Eyes

Hello, I need help with a stye infection that I no longer think is a stye. I had a huge lump on the inside of my right eyelid in 7th grade which puffed my eyelid up so it was hard to see. After a long time, it died down a lot but the lump has always been there very noticeably still and I am a senior in high school right now. Throughout the last 5 years, my eye have hurt alot for a few months and then the pain resides but the lump is always there. I have looked up many things to cure a stye and tried soaking my eye for very long periods every night but nothing seems to help. I also have started using eyedrops consistently for a few months now. I wear makeup but usually remember to remove it at night (some nights I am so tired, I sleep with it on but the next morning, I make sure to take it off) I also wear contacts and do sports but make sure I take them our everyday after school. Please help me because I do not know what it is or how to cure it. Thank you !
