Neuritis and neuralgia are the defeats of individual peripheral nerves connected with exposure of various etiological (that are causative) factors.
Neuralgia occurs during stimulation of sensory nerve fibres. In contrast, neuralgia, neuritis is characterized by pronounced changes in the nerve, gripping the myelin sheath (the inner part of the glial membrane of nerve fibers containing myelin) and the axial cylinder. Most often affects the optic, trigeminal, facial, auditory and radial and sciatic nerves.
The function of nerve trunks is to conduct impulses both centripetal and centrifugal in direction. Signs of dysfunction of the nerve (that are pain, paresthesia, paresis, vegetative disturbances) arise from the very beginning, when shell elements around the axial cylinders react on the harmful effects. This reaction is expressed in demyelination (that is to say destruction of myelin), as well as the proliferation of Schwann cells.

Only with the advanced process, the disintegration of axial cylinders occurs. In this regard, demyelinating and axonal neuropathy are spoken about.
In clinical practice, diseases of the peripheral nervous system are divided into neuropathy and neuralgia. When neuropathy occurs, there are clear anatomical changes in the nerve trunks, so there are clinically observed symptoms of loss: reduction of force, weight loss of muscles, inhibition of reflexes, reducing of sensitivity. Neuralgia anatomical changes are less pronounced or absent, the phenomenon of stimulation of the nerve is dominated, which are clinically characterized by attacks of severe pain, which can be combined with increased reflexes, sensitivity, and distortion of autonomic disorders.

How to treat sciatica? The most common method of treatment of sciatica is the application of heat: for instance, hot sand or hot water bottles. Roused dry sand (or table salt) is poured into bags and placed along the back of the legs. Widely used are both heating solux and blue light; ozokerite application is also prescribed, so as UHF and diadynamic Bernard currents.

Of the other physiotherapeutic means quartz, paraffin, galvanization with antipyrine and diathermy are also used. In cases of pronounced and persistent pain patients are sometimes intradermally injected with 15-25 ml of 0,25 – 0,5% solution of novocaine on the course of the sciatic nerve. This procedure can be repeated after 3-4 days.
There are useful injections of 5% solution of vitamin B1, 0.005% solution of vitamin B2. Inside headache tablets, aspirin, analginum and reopirin of 0.5 x2 are designated. When recurrent sciatica, spa treatment with the use of mud, sulfurous baths, massage is also effective, especially in the initial stages of the disease, and sometimes surgical treatment is agreed.
So, when there is such serious disease as the sciatica, you should conduct the treatment carefully with the very acute diagnosis process, having consulted with the good prepared specialists who have had enough experience facing the sciatica cases.
