<s>[INST] HI there my 15 year old daughter has had lower abdomen pain on her lower left side since weds (3 days ago) we saw out GP and he gave her a thorough check and suggested problem could be bowel or ovarie related and if no improvement we may need further investigations. She is mid- cycle but she said the pain is not like ovulating pain. She has not gotten any worse but is uncomfortable and the pain is moving around to the back area too.  There is no temperature.  She was given lactulose to have in the am for about a week or so to just rule out constipation issues.  I was going to take her to the doctors again in the morning, do you have any suggestions. Many thanks. [/INST] HIT hank for asking to ChatDoctorI really appreciate your concern for your daughter in my opinion this could be bladder cystitis, from the history given here this can be said, if I would be her doctor then I would treat her with the following medicines 1) Tab Ofloxacin 400 mg twice in day 2) Tab Dicyclomine with Acetaminophen three times in day if she fails to respond to this treatment then further investigation would be needed like X-ray abdomen and USG, hope this information helps you have good day. </s>
