I'm a normally healthy, 19 year old male - 5'7" tall and 220lb. I have been experiencing moderate, dull pain in my abdomen for approximately a week - this pain is generally focused on the lower part of my abdomen. However, if I press on the centre of my upper abdomen (directly below my ribcage), the pain is quite intense. I have experienced nausea (though just one instance of vomiting) and diarrhea (type 6/7 on the Bristol Stool Chart). I underwent removal of my gallbladder approximately two months ago which was followed by abnormal LFTs though these showed significant improvement at last test.
