Stomach Symptoms Can A Really Bad Head Aches And Non Stop Stomach Aches Be Symptoms Of An Ulcer?

Can a really bad head aches and non stop stomach aches be symptoms of an ulcer? - stomach symptoms

During the two days, until now I had stomach aches and headaches. I think bad too, if I move the hot flashes and lights when I leave. If these symptoms are from a stomach ulcer, can someone tell me. If you have symptoms of something like food poisoning, can someone back?
