Hello. Welcome to hcm.
occuring once a day might due to bowel problem or kidney problem. Diagnosis cannot be made unless investigated.
If you have problem with passing stools,vomiting
,nausea,then it can be a bowel problem or else pain while passing urine,urgency,back pain
,then it might be kidney problem like stones.
I advice you to take ultrasound
scan to rule out any abnormality and a cycle of pain killers.
All the best
