Final answer:
The symptoms of radicular lower back pain can include saddle anesthesia, loss of DTR's, bowel/bladder issues, and it is correct to say that all of the above are associated symptoms. Severe nerve compression may also result in other symptoms such as tingling in the extremities and neuromuscular disorders.
Step-by-step explanation:
The symptoms of radicular lower back pain can include a range of discomforts and physical dysfunctions. One symptom is saddle anesthesia, which refers to the loss of sensation around the buttocks, genitalia, and inner thighs. Another symptom is the loss of deep tendon reflexes (DTR's), which indicates nerve compression or damage. Additionally, patients may experience bowel or bladder issues, such as incontinence or retention, which can signify a serious condition like cauda equina syndrome. So to answer the question, the symptoms of radicular lower back pain that include saddle anesthesia, loss of DTR's, and bowel/bladder issues would be all of the above.
While not directly listed as options in the question, other red flags of severe radicular pain or nerve compression might manifest as hair loss, dermatitis, depression, numbness and tingling in the extremities, or various neuromuscular disorders, indicating the need for immediate medical evaluation.
