I have a herniated lumber disc. worried that i have had symptoms of diarrahea and what seems to be cystitus for past 5 days.

While it is difficult: to know if the bowel and bladder symptoms are related to the herniated disc, they might be. Typically lumbar nerve dysfunction which affects the bowel and bladder are motility issues: difficulty passing stool or urine. I would suspect the bowel and bladder issues are unrelated but your skilled primary care provider can help sort this out for you. Good luck with the disc!
