2 weeks of lower abdominal pain. taking miralax (polyethylene glycol) for constipation. motrin for abdominal pain. ?

Should be checked: Pain on the left side or under the belly button could be diverticulitis. R lower could be a chronic appendicitis. You state to be taking laxatives so I believe defecation is difficult. I would recommend a physician evaluation blood count to see if the white cells are up, a gastroentrologist or internist are good stating points but dont keep putting this off.

Needs physical exam: abdominal pain sometimes could be a sign of serious intra-abdominal conditions and other times it could be non specific. You did not mention nausea of vomiting or any fever or chills. I suppose bowel disturbance is your first differential. Are you eating enough fiber in your diet and drinking enough water? I would highly recommend you do that and if your symptoms persist you need to see an IM Dr
