Pain in the Thigh: Is It Really Sciatica? - Neurosurgery

Understanding pain in the thigh, particularly when it is described as a deep, dull ache that does not radiate down to the calf, can indeed be perplexing. The symptoms you describe, including localized pain in the back of the thigh and tenderness in the lower back, suggest that this may not be classic sciatica, which typically involves radiating pain down the leg due to nerve compression or irritation.

Sciatica is often characterized by sharp, shooting pain that travels along the path of the sciatic nerve, which runs from the lower back through the hips and buttocks and down each leg. The pain can be accompanied by numbness, tingling, or weakness in the leg. However, your description of a dull ache that does not extend beyond the knee and is associated with tenderness upon palpation of the lower back indicates that there may be other underlying issues at play.

One possibility is that you may be experiencing a condition known as myofascial pain syndrome. This syndrome is characterized by the presence of trigger points—tight knots in muscles that can refer pain to other areas. In your case, the tenderness in the lower back could be causing referred pain to the thigh. The fact that pressing on a specific point in your lower back elicits pain in your thigh supports this theory.
Another potential cause could be related to muscle strain or overuse. If you have engaged in activities that involve repetitive motions or prolonged sitting, it could lead to muscle tightness and discomfort in the thigh area. Additionally, conditions such as piriformis syndrome, where the piriformis muscle irritates the sciatic nerve, could also present with similar symptoms, although it typically involves more radiating pain.

It is also essential to consider the possibility of lumbar spine issues, such as a herniated disc or degenerative disc disease, which may not always present with classic symptoms. While you mentioned that your back does not hurt unless pressed, it is still worth investigating whether there is any underlying spinal pathology contributing to your symptoms.

Given that you have seen multiple physicians without a definitive diagnosis, it may be beneficial to seek a comprehensive evaluation from a specialist, such as a neurologist or an orthopedic surgeon. They may recommend imaging studies, such as an MRI of the lumbar spine, to rule out any structural issues. Additionally, a physical therapist could provide valuable insights into your condition through a detailed assessment of your posture, movement patterns, and muscle strength.

In the meantime, conservative management strategies may help alleviate your symptoms. These can include physical therapy focusing on stretching and strengthening exercises, heat or ice application to reduce inflammation, and over-the-counter pain relief medications such as NSAIDs (e.g., ibuprofen) if tolerated.

In conclusion, while your symptoms may not align with typical sciatica, they warrant further investigation to identify the underlying cause. Myofascial pain syndrome, muscle strain, or lumbar spine issues could all contribute to your discomfort. A multidisciplinary approach involving specialists in pain management, physical therapy, and possibly further imaging studies may provide clarity and lead to effective treatment options. Remember to communicate openly with your healthcare providers about your symptoms and concerns to ensure you receive the most appropriate care.
