I have been having mild periodic stomach burning. From just moving. Is this normal?

It is an alert. It is normal in that your body is trying to tell you something. Burning can be gastritis (inflammation of the stomach) perhaps an ulcer or just irritation after a virus. Something is amiss and causing you discomfort. Spicy foods, peppers, alcohol can aggravate. Acupuncture and chinese medicine can really help as can a visit with your physician if it has been occurring three weeks or more.
