I Have Been Throwing Up 1-2 Times Every Hour For

I have been throwing up 1-2 times every hour for 8 hours. I have been drinking liquids throughout but throw them up every time. I finally decided to try just saltine cracker an hour and a half ago so that I could keep down an ibuprofen. I have he'd a severe headache throughout this time, I don't think that I have a fever but sweat profusely each time I vomit. My jaw has felt sore in the past week.
