Are problems with urination related to having a ruptured disc?

Bad Disc & Urination. The lower back (lumbar area) overlies the area where nerves that control bladder function run. Should a bulging disc or narrowed canal irritate these nerves then increase in urgency or frequency commonly occurs. It is possible to have the bladder respond in the reverse, with retention of urine. If you have known disc problems and experience worsening urinary issues, contact your spine doctor.
