Sharp pain in eye and throbbing very painful and i tried flushing out but not working.

Scratch ?: You may have a scratched cornea, an abrasion, or even a foreign body, all of which would not just be "flushed" out with water or an eye irrigant. It is best for you to have a quick care MD check out your eyes (after hours I presume) and they can tell you what's going on. If the doctor needs an ophthalmologist to see you, arrangements can be made. Good luck.
