New contacs and one is really bothering me?

okay, long story short, last week i got conatcs for the first time, and they gave me dailies contacs. they were really nice, and i couldn't feel them, but they were wayy too expensive, so i wanted to switchbrands. but today i went in for the final fitting and i told that to my optometrist, and she put me on air optix for monthly use. I literally got them an hour ago,and one contact is really bothering me. I can feel it in there and it kinda stings/hurts. (i have the same power for both my eyes, so no i did not mix them up) what do i do? i go back in on saturday for my final final contact fitting. what do i do? eyedrops?
