hi these past couple of days iv been getting discomforting pains in my abdominal area. these pains usually last about 10-15minuets but only come at night when im in bed relaxing. when these pains occur and i go toilet either for a number1 or 2 these pains become more bareable. iv also been passing wind more frequently, and they really dont smell too good. i am a paranoid person so i also think the worst, 

does anyone know what this could be?
