Hi

For about 4 weeks now i have had this strange sensation in my left eye.
It started when i was tiling and managed to get a little piece of tile
in my eye. It came out fine but felt a bit sore as you would expect. It
didn't clear up in a couple of days so went to eye docs and they said
scratched cornea and gave some eye drops.

Took these and the 'something in my eye' feeling went away. But i am now
left with a sensation of my eye feeling swollen and sore however the eye
 looks fine and no sign of redness. I can also see out of the eye fine
and i don't wear glasses or lenses.

As this is now getting on for 4 weeks any ideas what could cause this
feeling of soreness? It feels like some form of inflammation but as i
said the eye itself is fine. I also have a slight viral type feeling and
i feel like there is a slight feeling of dripping down the back of my
throat type feeling so perhaps some form of sinus invlovement?

I know this is vague but has anyone got any ideas as to what this could be?

thanks
