What is radiculitis, why it develops and how it manifests itself.
Radiculitis - inflammation of the roots of the spinal nerves, which represent bundles of nerve fibers, bearing nerve impulses from the skin and muscles to the dorsal, and then to the brain.
Causes of radiculitis
The most common causes of radiculitis are spine diseases, in particular osteochondrosis, deforming spondylarthritis and hernias of intervertebral disks, that is, diseases that occur with a violation of the normal structure of the vertebrae.
In addition, radiculitis can be caused by influenza, tuberculosis, syphilis, rheumatism, tick-borne encephalitis, brucellosis, tumor of the spinal cord or its membranes and other causes.
Development of radiculitis in osteochondrosis contribute to:
- External factors - infection, trauma, overcooling;
- Internal factors - genetic predisposition of the musculoskeletal system or the features of blood supply to the spine; Congenital defects of the vertebral column or individual vertebrae.
The leading role in the mechanism of development of radiculitis in osteochondrosis plays the inflammation that develops around the intervertebral disc. Swollen tissues squeeze nerve fibers, causing them to disrupt blood supply, conduction and, accordingly, irritation of their structures.
Clinical picture of radiculitis
The first sign of a radiculitis is a characteristic pain, the location of which is determined by the position of the inflamed root. Periodically, the pain is interspersed with shots similar to electric shock.
Shortly thereafter, in the same area of the body there is a feeling of ants, tingling or numbness, after which the sensitivity of the skin in the area under the control of the affected root disappears. This means that a certain area of the skin ceases to feel not only the touch, but also the temperature and painful effect.
Later, with the spread of inflammation on a bundle of nerve responsible for muscle, to the data of symptoms joins muscle weakness in the same area, decreases or even disappear reflexes from the affected limbs.
After a few weeks of inactivity, the muscle is atrophied, and nutrition and blood supply may appear on the skin: badly healing ulcers and wounds, scleroderma, etc.
Often, this pattern is accompanied by symptoms that depend on the cause of radiculitis. This may be movement impairment in the corresponding parts of the spine, elevated body temperature, malaise and other general symptoms.
