I have severe pain in my stomach. I take a lot of pain meds to control back pain. Could I have an ulcer bleed? - back pain meds

The reason I ask, because the medication I am very nausious, if taken without food. For some time, when I throw up producing small amounts of blood on him. After last week had only withhin blood. There was a considerable sum. That worries me enough to stop taking the medication without food. Today I had a sudden onset of severe pain in the stomach. I think my question is, when it's time, a doctor is to see? Not to appear stupid to go to the Dominican Republic for gas pains.
