What Does A Stomach Ulcer Feel Like?

The symptoms for a stomach ulcer are that the sufferer feels like he's having slight pain in his stomach. In the beginning the person usually ignores the symptoms and it is at this stage he is making one of the biggest mistakes of his life; the ulcer can turn into cancer if not taken care of and then the person has very less chance to see the beauty of the world for long period of time.
      
Sometimes the person also feels that he is having a hard lump in his stomach and if the above mentioned symptom and the lump combine together in one person, he should immediately consult his doctor to get it removed from his body. If he doesn't, the problem can be fatal for him.

I have been having pain in my stomach for about three years.  It feels like its an empty feeling kinda like when you haven't eaten in a while. It hurts really bad and i dont know what to do.  What do you think it is?
