Pains in abdomen and back?

For the past day I've had pains throughout my abdomen, back, arms, and hips. It's a sore, dull pain. I'm also feeling kind of drowsy and a little sick to my stomach. It's mostly around the top right of my stomach, navel, lower part of my abdomen, top left of my back, left arm, and hips. My period should be coming soon but I've never experienced this before. Also, they don't feel like period cramps. What could this be? Should I see a doctor if it gets worse? Is there anything I can take?
