Should you go to the e.r for intermittent saddle numbness? i heard that saddle numbness is an e.r worthy symptom

No: A cluster of more serious symptoms that would warrant a trip to the Emergency Department would include: Localized sharp lower back pain, bladder or bowel incontinence, sharp/stabbing pains in your lower extremities, or weakness in your legs or feet. The issues you are having should be addressed with a physician in the office who can perform a more detailed neurological exam. Best of luck!
