Baby won't sleep

My girl has been an awesome sleeper since the begining. These past 2 weeks have been hell and it only seems to be getting worse. Tonight she was up at 12 wouldn't go back to bed until I gave her a bottle I tried everything! Finally got her down she woke up at 2:45 same thing wouldn't sleep gave her a bottle and she is still not going back to sleep. It's now 4:05. I am completely against CIO it's just not for me but tonight I figured I have no other choice. She cried and cried and cried you would have thought her crib was on fire she never stopped. My husband is now rocking her for the 10th time she just won't go down. I am at a complete loss I don't know what else to try!

We also gave her some Tylenol before bed she seems to be teething. But even that didn't work. Im exhausted and frustrated.
