Amputation is the only solution.

If it’s a sty, I wouldn’t touch it. It will resolve on its own. You could get a bad infection if you mess with it.

I've had that problem for a long time, but a much worse case. For almost a year, I struggled with eye drops and ointment. In the end, I resolved the issue very quickly and easily by massaging my eyelids with baby shampoo and lukewarm water.
