For about 2-3 weeks I have been having light continuous stomach pains which leave every now and then but then near the end of the 3rd week I get 'the runs'. the pains seem to concentrate to the middle of my stomach. Have I caught a virus causing the runs 'IBS', these regular stomach pains, have they just become a habit? I can eat, drink, walk excetra excetra... If these regular stomach stomach pains are in fact a habit, how do you lose it? Please help.
