I have had stomach aches for about 2-3 years now. They come almost every day, and they have gotten progressively worse. I used to just feel bloated, but now I feel nauseous as well. I am at the point where I have to stop everything I am doing to lay down because of how horrible I feel. I am a vegetarian (I take a multivitamin every day), but I am not vegan. Could I have lactose intolerance? I sure hope not (I love my icecream!), but should I try to go without lactose for a week? Why do I have stomach aches all the time?
