Cruralgia - Causes and Symptoms


Cruralgia is a pain that radiates along the anterior and / or internal aspect of the thigh, ie along the course of the crural nerve.

This symptom can arise violently (as happens, for example, after an effort to lift weights) or progressive. Sometimes pain in the crural region can be associated with back pain (lumbocruralgia). In severe cases, this manifestation is accompanied by numbness, a burning sensation, tingling and weakness in the affected leg.

Cruralgia can result from an irritation and a compression of the roots of the crural nerve at the level of the L2-L4 vertebrae (lumbar disc-radicular conflict).

In most cases, crural nerve pain results from a herniation or a protrusion of an intervertebral disc.

Other possible causes of cruralgia include bony irregularities (secondary to vertebral fractures, osteoporosis, arthrosis with formation of osteophytes etc.) and narrowing of the vertebral canal (lumbar stenosis).

Cruralgia can also be favored by incorrect postural habits, overweight and a sedentary lifestyle.

Less frequently, this manifestation is caused by tumors and systemic diseases such as diabetes, hyperparathyroidism, hyperthyroidism and multiple myeloma.
