Hello and welcome to HCM. As an
Urologist,i can understand your concern.
The kidneys aren't located in the groin area,but in the loin region.!!
To know the cause for your pain,you'll need to do a CT-KUB scan.
That will clear your doubt about stone and if your pain is due to it.
Also,it may give some idea about your
hip pain.
According to the report,an expert opinion can be given,about treatment.
You may take an anti-spasmodics for pain relief,if the pain is severe.
If you've any doubts,send all the reports,to me as a direct question.
Dr.Matthew J. Mangat.
