Have a hern @ l4-l5. Lately pain is x2from back down tofeet (bi-lateral) along w feeling bladder always full, constip (no meds)& weakness in legs. Worry?

Being treated? Since you mention the disc herniation i would assume that you have had an MRI of the lumbar spine. Having pain in both legs to the feet is less common with a herniation unless it is very large causing central canal stenosis. The herniation may not be the source of your issues. Abdominal abnormalities can also cause back pain but that may not explain the leg symptoms.
