Every ailment has a moderate start and peptic ulcers are no exception to the rule. 90% of the people present themselves to the doctor only after complaining of pain. The pain could either be mild / dull or intense or a rather slowly progressing pain on the upper abdomen area. Generally a feeling of a heart burn should ring alarm bells. More clearly, if there is a burning sensation or pain somewhere in between the chest and the belly button; it can be signs of ulcer. The burning sensation or pain either lasts for few minutes or can last for few hours. This sensation of course can recur.
