Upper left quadrant pain

I am a little concerned. Three days ago I started to have a sharp almost burning pain in my upper left abdomen.  The pain goes from a sharp feeling to a dull ache, but it always there.  I am a healthy 28 year old female.  I had my gallbladder out in January of this year.  I called my doctor and they can not see me until Tomorrow.  Just wondering if anyone has any ideas of what this could be.

Thanks
Becky

By now you've seen your doc.  What was the verdict?  I'm wondering if your pancreas is involved.

Went to doctor and they think it is a ulcer. I guess time will tell, but no relief of pain yet.

About a week ago I started having pain in my left upper back.  I have Acid Reflux Disease and take Pepcid AC constantly.  I went to the Doctor and he is sure I am having problems with my heart and scheduled a Stress  Test.   this is not the first time and not my first Stress Test.  Do I need another Doctor? What result on lab would show up if I am having pancreatic problems?
