I had this happen a couple of years back. I thought it was conjunctivitis, and so did the regular (non-eye) doctor I went to. As a result, whatever it was, did not get cleared up and it turned out rather bad. I too had to use the drops every few hours with an alarm. Also, the drops I got had to come from the "serious" pharmacy (not just your regular one, but the special made to order place). Also, it hurt. Was it the most painful thing ever? No. Right now second degree cooking oil burns all over my hand holds that spot, but it was a near second.
Oh, and when I did get to the opthamologist he decided to do a "culture". There I am in the chair, mostly blind, leeking yellow colored dye out of the corners of my eyes thinking, "Wait a minute, if I were going to do a culture of something I would...Oh, great googly-moogly is he seriously burning that wire so he can stick it in my eye?!?" Yep, and he did. Wasn't actually that bad.
No soft contracts ever again. No contacts period for 3 months. I've got a scar on my cornea that now will make it difficult for me to get laser surgery. Basically, I'm all but stuck with glasses (hard contacts are for the birds). But it turns out I was lucky, really. It could have been a lot worse.
