Thanks for your query.Based on the facts that you have posted it appears that you have severe pain
in lower abdomen on holding your urine for a long time especially in the morning.
This is most likely to be due to bladder spasm which commonly occurs on holding on urine for long time.
Please get your routine urine analysis and culture done to rule out infection.
Please take urinary anti spamodics like Oxybutinine twice daily for 2 weeks.
Get the prescription of medicines from your family Physician.
