increasing stomach pain and more food?

HI, i will get down to business right away. i have this pain in my stomach for few days allready that keeps growing every time i stop eating for 2-3 hours. whats intresting about it is that whenever i eat even small candy the pain goes away for 1 hour at least. As more i eat as more time i have without feeling any pain in my stomach. This is second time i am having this problem, last time it lasted 2 weeks and i managed to last ok, then it disapeared for 4 months. Now it started again, i just have to eat something to stop the pain. And yes the pain is nothing like the feeling of hunger, this pain increases production of saliva in my mouth making me want to puke. i cant even sleep through the night because night lasts more hours than the food in my stomach. What i have discovered is that i am not even hungry to the food, its just something in my stomach that is asking for food more and more, please tell me whats could be the problem and should i see the doctor?
