Depends on what is causing it. You may want to rule out infection with a urinalysis as well as urine tests for gonorrhea and chlamydia. Diabetes can also cause nerve dysfunction. A blood test can be considered to screen for this not uncommon cause.
If the tests remain non-revealing, you may want to consider a referral to a urologist or neurologist for further evaluation.
Followup with your personal physician is essential.
