Sometimes my eyes itch extremely bad and there feels like theres a lot of pressure on them (specifically that little ball on the inside corner of eyes), and I rub them for a minute or 2. Throughout this process, and a little after, my eyes secrete liquid. But not like regular tears, the liquid is thicker, and STINKS. It smells kind of like onions. I ve always been curious as to what this liquid is? Why does it smell? And why is it so relieving to do this process? I feel like I m milking my eyes.
