Hi, many thanks for the query!
Yes, it can be calculus related pain, you need to do certain investigations
to confirm it, viz. USG (KUB), X-ray KUB, Sr. creat., Sr. BUN, Sr. Uric acid,
Urine (Routine & Microscopy).
For time being, you may take anti-spasmodics, pain killers, diuretics as per
your doctor's opinion.
Get physically examined by your doctor for hip bone bruise
Wish you a good health.
