Hello! I read carefully your query and understand your concern. If you don t have upper abdominal pain,heartburn,nausea,vomiting,weight loss and you are eating well without problems I think your stomach is fine. This pulsating sensation in your stomach may due to your anxiety because when you are in stress your heart beat faster,the pulse increase and blood pressure in major body arterias ,such as abdominal aorta and your neck arteries, is elevated and you might feel this like a pulsating sensation on stomach and neck. Despite this I suggest to consult a physician so he can do a physical examination and evaluate if this pulsating sensation is objective(he can feel this by palpating/touching your abdomen) or it is just your sensation. If this is due to anxiety you will feel better after the confirmation of your doctor. Hope my answer has helped. Take care. Dr.Rovena
