What Causes Feeling Of Roughness On Surface Of Eye When I Blink?

i was hit in the eye with a hockey stick and my entire eye was filled with blood. I went to the eye Dr. and he said that I had a Suconjunctival Hemorrage, it has been a month since the injury, all the blood is out of my eye and the bruising is gone, but my eye still feels rough on the surface when i blink my eye?
