Thanks for your question on Healthcare Magic. I can understand your concern. Yes, herniated disc at the level of lumber vertebrae can cause urinary incontinence. So your urine leak without knowing you is due to herniated disc. Chronic pain causes stress on the body. This continuous stress causes sympathetic over activity and this in turn causes rise in blood pressure. So your uncontrolled blood pressure is also due to pain because of herniated disc. So pain management is very important to control your blood pressure. Along with this, you will also need anxiolytic drugs too reduce stress. Consult pain specialist for local steroid injection for better pain management. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
