The pain caused by a stomach ulcer can travel out from the middle of your tummy up to your neck, down to your belly button, or through to your back.
It can last from a few minutes to a few hours, and often starts within a few hours of eating. You may also wake up in pain during the night.
Taking indigestion medication (antacids) may relieve the pain temporarily, but it'll keep coming back if the ulcer isn't treated.
Less common symptoms of a stomach ulcer can include:
Some people also find they burp or become bloated after eating fatty foods.

- vomiting blood – the blood can appear bright red or have a dark brown, grainy appearance, similar to coffee grounds
- passing dark, sticky, tar-like stools
