Sciatica?
Hello Dr.
Ding,
My father is 71 years old and generally in good health, but in recent years, he has been experiencing difficulty with his left knee when going down stairs, although he has no issues going up.
Recently, after descending stairs, he often feels numbness on the outer side of his left thigh, which even affects his ability to walk, requiring him to sit down and rest before he can walk again.
After a doctor's diagnosis, he was informed that it is sciatica, but after taking medication, not only has there been no improvement, but the pain has actually worsened.
I would like to ask, if it is indeed a condition related to the sciatic nerve, which specialty should he visit for a detailed examination? Or are there other specialists that should be consulted as well? Thank you!

Dr. Ding Xianwei reply Neurosurgery
Based on your description of your father's symptoms, there may be two issues: one is degenerative arthritis of the left knee, and the other could be lumbar spinal stenosis causing nerve compression, which leads to intermittent claudication.
However, this assessment is based solely on written information, and it is advisable to have a face-to-face examination by a neurosurgeon at a hospital.
If you have further questions, feel free to reach out again, or you may visit my outpatient clinic at Taoyuan Hospital, Department of Neurosurgery, every Monday and Wednesday morning.
Wishing you health and safety.

More Info
Sciatica, commonly referred to as sciatic nerve pain, is a condition that arises from irritation or compression of the sciatic nerve, which runs from the lower back down through the hips and buttocks and into each leg. The symptoms can vary widely, but they typically include pain that radiates along the path of the sciatic nerve, often characterized by sharp, shooting pain, numbness, or tingling sensations in the leg. In your father's case, the symptoms he is experiencing, particularly the numbness in the outer thigh and difficulty descending stairs, are indicative of potential sciatica or other related conditions.
Given your father's age and the symptoms described, it is essential to conduct a thorough evaluation to determine the underlying cause of his discomfort. Sciatica can be caused by a variety of factors, including herniated discs, spinal stenosis, degenerative disc disease, or even muscle spasms in the buttocks that can compress the sciatic nerve. The fact that he experiences increased pain after taking medication suggests that there may be an underlying issue that requires further investigation.
To diagnose sciatica, a healthcare provider will typically start with a detailed medical history and a physical examination. They may assess your father's range of motion, reflexes, and muscle strength. Imaging studies such as MRI or CT scans may be recommended to visualize the spine and identify any structural abnormalities that could be contributing to the nerve compression.
In terms of specialist consultations, it is advisable to start with a visit to a primary care physician or a neurologist. A neurologist specializes in conditions affecting the nervous system and can provide a comprehensive evaluation of the sciatic nerve and its function. If the neurologist suspects that the issue may be related to the spine, they might refer your father to an orthopedic surgeon or a spine specialist for further evaluation and potential treatment options.
Physical therapy is often a critical component of treatment for sciatica. A physical therapist can develop a tailored exercise program to strengthen the muscles supporting the spine, improve flexibility, and alleviate pressure on the sciatic nerve. In some cases, additional treatments such as epidural steroid injections may be considered to reduce inflammation and pain.
If conservative treatments do not provide relief, surgical options may be explored, particularly if there is significant nerve compression or if your father's quality of life is severely impacted. Surgical interventions can include discectomy (removal of a herniated disc), laminectomy (removal of part of the vertebra to relieve pressure), or spinal fusion.
In summary, for your father's condition, it is crucial to seek a thorough evaluation from a neurologist or orthopedic specialist. They can provide a comprehensive assessment and recommend appropriate diagnostic tests and treatment options. Early intervention can significantly improve outcomes and help manage symptoms effectively. It is also important to communicate openly with healthcare providers about the effectiveness of any treatments and to explore alternative options if current medications are not providing relief.
