Do I have an ulcer?

I am having abdominal pain.
I loss my appetite on eating.
Like I want also to vomit.
This occurs on and off sometimes.
Please help me. Thank you!

It could beā€¦Burning pain is the most common peptic ulcer symptom. The pain caused by the ulcer is aggravated by stomach acid coming in contact with the ulcerated area. Using the endoscope, your doctor see for ulcers.
