Hi welcome to Health care magic forum.
Thanks for calling H.C.M.F.
Most probable cause might be urinary tract infection
, If female gynacological problems may be possible.
I advise you to consult an urologist
, for diagnosis and treatment. You may have to get M.R.I. besides other routine tests for confarmation.
Avoid taking spicy foods, junkfoods, and oily foods to avoid gastro intestinal irritation.
Wishing for a quick recovery.
