Since the birth of my baby 1/09/04 I have been getting periodic stomach aches. I did experience nausea throughout most of my pregnancy up until delivery, but I just related it to pregnancy. Now that I have read about biliary colic, I think that is what I have. I have higher cholesterol, and I get a very upset stomach ache after eating and it gets worse in the evening. I kind of feel sick when it comes on too. Like i'm coming down with a virus or something. Does this sound like a gullblader thing or stomach ulcer?
