Every now and then I have this intense pain in the top of my right eye. It feels like there is something in my eye but nothing is there. I can't close it, move it, touch it, nothing, without it causing the pain to become more intense. This has only happened to me a few times (maybe once a year) but the pain is so bad, I'd rather have my eye removed. It feels like something is poking it. I had a bad episode this morning. I woke up around 4:30am and as soon as I opened my eye, I gripped the bed in pain. It makes me cry and want to punch something. Any advice as to what it could be?
