Why is my stomach hurting?

Q: I am a 29 years old male, doing a clerical job. Since the last 4 days, the left side of my belly is paining. It pains when I press that area. And sometimes even without pressing it pains. What could be the problem? Please tell.

A:This could be possible due to acidity. I would advise you to take Nexium 40 mg for 2 weeks. If you dont feel better, you need to get an ultrasound of your abdomen.
