I don't know what abdominal pain when pressed on the tummy is but was embarassed to admit it. Can someone tell me?

See your doctor. This could bea sign of something serious going on inside your belly. It's hard to tell with the info you gave. Pain is nothing to beembarassed about, it is a symptom which needs to be evaluated. See your doctor.
Explanation. It just means pain when someone pushes on your belly.
