eye infection/pain what could it be?

hi im in a time crunch and i was just wondering if you could really help because i could really appreciate. so basically i wear contacts started for maybe two months havent really had any problems except when yesterday felt a small pain whenever i blinked but just ignored it as i was quite busy. though today in the morning the pain started to continually start the pain and now it hurts so much i cant even endure it. i have to admit, in the mornings im in such a rush i dont bother to wash my hands before wearing my daily contacts. the pain is in the corner of my left eye, and it feels like it has a place when i hav my eyes wide open but when its closed it hurts a lot and there is a stingy pain. i cant really even blink really pain. please help, like wat it could be, wat i could do becuz i cant see the doctor until tomorrow or even later. also would like to ask whether see my contacts doctor or the regular doctor like for colds etc? THANKS
