Hi Tanita,
I enjoyed your discussion post reviewing case study #1 and the differential diagnoses provided. However, further information is required to thoroughly examine and diagnose this patient. Depending on the length of time the patient has been experiencing this pain, it could be useful to obtain an Xray or CT scan to examine the condition further.
My primary diagnosis for this patient would be sciatic nerve pain due to the pain in the lower back traveling down the left leg. Often sciatic nerve pain is described as sharp, stabbing, jolting, shooting, and even throbbing (Cleveland Clinic, 2020). Typically, this pain is due to inflammation or pinching of a nerve in the lower back (Cleveland Clinic, 2020). To assess for this condition, it is important to perform several tests. The straight leg raise test will help pinpoint if there are any affected nerves or disks in the back (Cleveland Clinic, 2020). Another test to perform would be a spinal Xray to examine for fractures, infections, and even back problem (Cleveland Clinic, 2020).
A herniated vertebral disc is a great potential diagnosis for this patient because the patient can experience pain that may radiate down the legs and associated numbness. With a herniated vertebral disc, depending on the severity, patients may have no symptoms or may experience pain, tingling, burning, and numbness to the affected side (American Association of Neurological Surgeons, 2022). Further diagnostic testing is required to determine if this is an accurate diagnosis for the patient.
I also agree that spinal stenosis is a potential diagnosis for this patient. Spinal stenosis is the narrowing of the spinal canal and the pressure can result in lower back pain that radiates down the buttock into the thigh (Garrick, 2020). A common cause of spinal stenosis is arthritis, which is a potential cause of this diagnosis (Garrick, 2020).
The differential diagnosis of a urinary tract infection is unlikely based on the patient having pain that radiates down the leg. However, UTIs can cause lower back pain in some patients. However, most of the time, UTIs that do cause back pain will be described as mid-back pain and also radiate into the groin area (Center for Family Medicine, 2020). Therefore, it would be a good idea to obtain a urine sample to rule out infection to be safe.

Diagnostics/Lab Tests and Results:
CBC – To evaluate for spinal infections
CSF analysis- For suspected spinal infection or inflammatory etiologies
X-ray of the spine- for flexion-extension views to identify spondylolisthesis and spinal instability.
MRI of the spine- to assess for suspected myelopathy or radiculopathy.
Electromyography (EMG)- to confirm compressions caused by spinal stenosis or herniated disks (Urits et al., 2019).
Assessment:
Differential Diagnosis (DDx):
- Sciatica: This condition is characterized by pain that normally radiates along the sciatic nerve path, which branches from the patient’s lower back through to the buttocks and hip, and down to each leg (Kim et al., 2018). However, sciatica normally affects one side of the body. The patient in the provided case study presents with lower back pain that radiates to the left leg, which is a great indication of sciatica as the primary diagnosis.
- Lumbar disc herniation: LDH is characterized by lower back pain and is common among adults between the age of 35 and 50 years. It normally results from changes in the structure of the lower lumbar spinal disk between the 4th and 5th vertebrae and between the 5th lumbar vertebra and the 1st sacral vertebra (Benzakour et al, 2019). Most patients normally present with symptoms such as lower back pain, radicular pain, limited trunk flexion, and weakness at the lumbosacral nerve roots distribution. The patient in the provided case study displayed lower back pain, however, an MRI of the spinal column is needed to confirm this diagnosis.
- Lumbar spinal stenosis: LSS is associated with narrowing of the spinal canal located in the lower back resulting in pain. Stenosis causes pressure on the patient’s spinal cord or nerves connecting the spinal column and the muscles (Deer et al., 2019). As such patients will present with lower back pain just like the one in the provided case study. However physical examination is required to assess for the presence of loss of sensation, abnormal reflexes, and weakness to confirm this diagnosis.
- Lumbar muscle strain: LMS is described as an injury to the lower back characterized by mild to moderate lower back pain. The injury can lead to damage to the muscle or tendons causing spasms and soreness (Urits et al., 2019). An x-ray is however needed to confirm the impact of the injury on the tendon or muscle to confirm the diagnosis
- Ankylosing spondylitis: This is an inflammatory disorder, that can lead to some of the spinal bones fusing over time. It is characterized by pain in the joints and the back (Ogdie et al., 2019). Symptoms normally appear early in life, including reduced flexion of the spine. The patient only presented with back pain which radiates to the left leg with no joint pain or reduced flexion of the spine.
Primary Diagnoses:
1.) Sciatica
