got a scrape of eye ball missing in the white of my eye - what to do?

[mooseloose]

Eye started really watering - I don't know why, so of course i rubbed it. But anyway I can see that there is actually a piece of white scraped away! It's like a slash dent! I looked on NHS and it says don't worry! It's red and I had a headache earlier (gone now) and its uncomfrtable to blink. Any one else had the same? Thanks

thanks both - amd just going to go off and find mirror to have another peep at eye - headache again. yikes!
