Has anyone heard of lumbar mass causing overactive bladder symptoms? I originally presented with sciatica sympotoms down my left leg. After some tests they found a "cystic-like mass in the left lateral recess behind the L4 vertebral body of my spinal column." The mass is sitting on or part of the nerve root. L3-L4 disc protrusion was also detected. Since last winter i have been experiencing what i would call overactive bladder symptoms, urination urge increase, urination multiple times a day, no leakage. I'm a 23 year old male. How likely do you think my spinal issues are causing the bladder issues? Any advice would be truly appreciated.
