<s>[INST] my boyfriend has mid-lower abdominal pain and sort of loud bubbling noises in lower stomach. he was doing sit ups 3-4 days ago but it s not pain from the sit ups he thinks. what do you think it is? [/INST] Welcome to Chat Doctor, Setups can cause abdominal pain especially on the sides of abdomen but very rarely in mid-lower abs. About those loud bubbling sounds, it just makes sense to mention that these are just intestinal sounds, but they are usually not so audible as your boyfriend seems to claim, but if it is so then maybe you got to ask him how has been his bowel habits recently, very constipated or too much vigorous to cause diarrhea.  He can just eat himself examined by his Primary care physician who can assess him clinically and then advise accordingly. Hope your queries have been answered well. Have a healthy life. </s>
