Neuralgia is characterized by pain, propagating in the course of a nerve, and usually not accompanied by significant violations of the functions of the organ or muscle. Depending on which nerve is affected, we can talk about various types of neuralgia. For example, sciatic nerve neuralgia is more common, so as trigeminal neuralgia and neuralgia of the occipital nerve.

So, let us speak about symptoms. Neuralgia of the sciatic nerve is characterized by the presence of more or less sharp pain along the sciatic nerve. Usually sciatica develops acutely; sometimes pain precedes the appearance of discomfort in the leg, in the lumbar region, patients complain of a feeling of heaviness in the leg, on fatigue in it.

Pressing the course of the sciatic nerve is sharply painful. Usually there are the following pain points: in the gluteal fold in the popliteal fossa and behind the inner ankle. Permanent sign is pain along the nerve during stretching it, revealed in the examination of Lasegue. The above symptom is examined in this way: the patient lies on his back, straightene his raised up injured leg. At the time of lifting of the legs the patient notes pain across the back of it, with legs bent at the knee joint pain along the way, the nerve disappears. The same pain arise if the patient tilt the torso forward and down, without bending his legs in the knee joints (to get the floor with his hands).

Often when sciatica occurs, lateral curvature of the spine can be marked, it is reflexive protective posture. In this position, pain subsides.
The causes of neuralgia of the sciatic nerve are varied. Often in cases of persistent sciatica we can reveal pathological changes in the vertebrae in violation of their shape, which leads to traumatization of the nerve roots that go through the intervertebral holes. Sometimes the cause of sciatica is transferred infection (influenza, malaria and rheumatism), some gynecological diseases, as well as local cooling, cold moments.

In cases when the neuralgia of the sciatic nerve is conditioned by stimulation of the lumbar and sacral roots, we can talk about sciatica. In these cases, patients complain of back pain with dedication in the leg or both legs. Pain of these is amplified at the slightest movement. So, lying on the back, the patient experiences increased back pain when lifting his head, in laughter, coughing or sneezing. Especially difficult the transition from the horizontal to vertical position and vice versa is.
Duration of acute neuralgia of the sciatic nerve or lumbosacral radiculitis is from 2 to 6 weeks. This can include lucid intervals of several days with subsequent worsening of pain.
With more prolonged and protracted course of sciatica we should carefully examine the spine, as well as exclude neoplastic process in the spinal cord or pelvic organs. In the latter case, except for pain symptoms, signs of neuritis show themselves: diminish or disappear tendon reflexes, muscle atrophy appear, reduced or completely extinguished pain sensitivity comes.
