Hi,
Noted the history about your daughter of 7 and understood the concerns.
Stomach ache in a child can be due to many reasons like worms,
appendicitis, abdominal lymph node enlargement and obviously fecolith formation as your Doctor has suggested.
Noted that she was prescribed 3 ex-lax stat and a cal full of
miralax but have not told about the reduction of pain or so.
These medicines can cause mushy stools and changes as per their action on colon and bowel.
So nothing to worry unless there is
bloating, pain in abdomen, nausea or
vomiting.
You can get the following investigations:
X-ray of abdomen in standing position to know about fecoliths.
Ultrasonography of abdomen to rule out appendicitis, lymph node enlargement.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
