This kind of pain interferes not just to live but even to walk. How is it that pain arising in the back, able to penetrate into the limb and cause lameness? Although the source is much higher, we feel its impact at that distance: back is sore, but numb and drag his feet. How the back pain radiates to leg?
Causes radiating pain in the legs can be draft, low back pain, hernia, tumors and stress
This is due to a reflex nervous nature of pain, its ability to spread across the entire length of the nerve emerging from the spinal cord. If this nerve somewhere is irritated, there is a distant response.
One of the possible causes of foot pain can be inflammation of the sciatic nerve
In the lumbosacral plexus is the nerve fibers emerging from the vertebrae l4, L5 and S1 — S3. This plexus is called the sciatic nerve. From the comfort of your piriformis, it literally splits at the thigh and ankle muscles and joints, being the most powerful and longest nerve in the human body.
Sciatica responds thus in the lower extremities. Pain appeared in the lower back to the legs, called lumbosciatica. Usually suffers (is ill or pulls) one foot on the side of the nerve, but it happens and two-way reaction in which both feet hurt.
The pain is not limited to, patient stalking and other unpleasant feelings:
If the nerve is affected at the level of the sacrum, through the muscles of the buttocks and thighs, pain syndrome from the sacrum and up to the foot is called sciatica.
Very often people feel pain in back and leg in two different categories and not see the root cause. "I have a pain in my right knee, numb foot. I can't come on foot and climb the stairs" — they describe in detail the condition of their limbs, forgetting about the pain in the back, which all preceded it. Surprised also, "incompetence" of doctors who, instead of treating knee osteoarthritis, all of a sudden begin to engage the spine.
But it is the spine, with its complex nervous, muscular-ligament and the vascular system is the root cause of sciatica.
Why get sick, pull and numb feet
Classification of the pain syndrome of the back and legs
In its origin all kinds of back pain radiating to limbs, can be roughly defined in three main groups:
Here you can put all of DDP (degenerative processes), because of which violated all the metabolic processes in tissues and their diet, and infectious, inflammatory diseases and congenital dysplasia of the spine. The threat to the nerve fibers here is twofold:
Vegetative-visceral disorders — this is a huge symptom, which includes all disorders in the internal organs and body systems related to impaired adjustment of the autonomic nervous system (ANS)
The autonomic system is closely connected with the Central principle of direct and feedback:
Especially often problems with the feet can occur when vegetative-vascular disorders in the area of the lumbosacral spine. Poor blood supply can lead to pain in the back and limbs, muscular dystrophy of the legs.
Summarizing the above, we can conclude:
To find out why sick, pull and numb legs because of the pain originated in the back, only after a thorough diagnosis:
The treatment of back pain and legs
Treatment should be fully adequate to the causes of the disease.
Treatment reflect pain is always a long process, as they usually occur in chronic long-standing diseases that affect the human nervous system
Therefore, if a backache, try to immediately determine the cause of the pain and start the treatment without waiting for the moment when you start to hurt, go numb or pull your feet.
If the pain radiates to the leg, first think about lumbago (sciatica) or sciatica. Especially if your fingers go numb and my leg aches. Most often the case. And few people remember that such symptoms can be and at other diseases, such as acute appendicitis.
Important: About rare diseases, leading to the emergence of the described syndrome, should not be forgotten.
Pain in the lower back, associated with disease of the spine and extending to the lower limb, called lumbosciatica.
Degenerative process in the lumbar spine the pain is often develops due to the compression of a nerve root and radiates to the lower limb on the main nerve of the lumbosacral plexus, the sciatic, which is divided into fibular and tibial. The latter gives the popliteal fossa rise to nerves of the lower leg.
Compression of nerve roots occurs when the destruction of intervertebral cartilage on the background of degenerative reactions. This decreases the distance between adjacent vertebrae and, consequently, be less openings for the spinal nerve roots. When herniated, they get annoyed directly by the protrusion of the hernia, in tumors, abnormal tissue growths, while spondylosis is bony overgrowths, called osteophytes.
On the background of pathological process is always evolving inflammatory reaction in the form of edema and dysfunction of the surrounding tissues, worsening the blood circulation of the affected area, are inhibited normal metabolism. Resulting increased muscle tone in the area of innervation of the roots of the disadvantaged, which leads to a strengthening of pain.
The development of changes in the spine usually marked with the end of the process of ossification approximately 25 years and is considered a normal physiological phenomenon. This early aging bone and cartilage structures can be suspended, if you follow the principles of proper nutrition and strengthen the back muscles with special exercises.
Diseases of the spine occur in the following types of sciatica:
Important: the Most common pain syndrome is mixed. One form of sciatica in its pure form is rare.
Chronic pain is almost a constant companion of life to which almost used, as the lucid interval is very small. Thus pulls in the lumbar region and along the branches of the sciatic nerve.
With the development of pain syndrome may develop paralysis of the lower limbs caused by a complete compression of the motor rootlets. But more to such severe consequences of pathological process did not get it.
Often lower back pain radiating to the leg, are a manifestation of diseases of internal organs. Limb while this numbs, the nerve pull, and the pain may also be given in the groin.
These phenomena are explained by the peculiarities of the innervation of the pelvic organs and legs.
