What do you use for a stomach ache?

Doc. has removed gallbladder, but the pressure is in front at stomach level on the left-ish side. 
I haven't felt much like eating today. But I think the Pepto is giving me some relief.

Still have the appendix.

If you still have pain on Monday, you must be seen by a doctor.   And if the pain gets worse tomorrow or Sunday...go to the emergency room.

OK.  If not better by in the morning I will call in for a Sat. morning appt.

I appreciate all the response to my inquiry.

Where is the pressure?
