It appears that you may have gastritis. Gastritis leads to nausea and pain in the stomach. Symptoms may involve feeling sick in your stomach or having discomfort in your belly. This can be brought on by spicy or acidic foods, stress or certain drugs. Try eating less food more often, staying away from things that cause problems, and finding ways of managing stress. You must speak with a gastroenterologist who will be able to give you the right diagnosis as well as the treatment plan needed for your recovery process.
