Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
This pain may be having many reasons like:
1. Intestinal colic
2. Origin may be from urinary tract
3. It may be musculoskeltal
So I will advise you to visit a doctor who will examine you personally and treat you accordingly
I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
