2 days ago, my stomach started hurting really bad, i noticed it felt hard, and it must have not digested the food. i took pesto bismol. and every morning, it hurts really bad. what else can i do?

You need to see a doctor and have this pain evaluated. There can be many reasons to be having abdominal pain ranging from constipation to appendicitis. Pain that is lasting more than 2 days needs to be evaluated. So, call your doctor or go to urgent care. You need to have this checked. Good luck to you!

It is never normal to have severe abdominal pain. Severe pain almost never comes from not digesting food well. You should see your primary doctor to have the cause of the pain evaluated and treated. If the pain is severe, do not delay. Good luck.
