Fortunately, around us there are many happy people who will find it difficult to answer the question of where is the sciatic nerve. This means that they have never experienced those burning pains, resulting in its inflammation, which is not allowed to move. Why inflamed sciatic nerve what to do if you find yourself with this disease? How to recognize and how to deal with this disease, describe below.
What is the sciatic nerve
Anatomy calls the sciatic nerve the largest nerve in the human body. In the adult, its diameter can reach one centimeter. It is a derivative of the sacral nerve plexus, which, in turn, formed of two lumbar and three sacral segments of the spinal cord. Taking the start in the pelvic nerve through the hole of the Ilium, leaves it, and, passing between the muscles of the buttocks, enters the thigh beneath the bottom edge of gluteal muscles. Going down the back of the thigh it gives several branches to the innervation of the hip joint and the muscles of the thighs and buttocks, and then, at the level of the popliteal fossa, splits into more - and peroneal branches, which, in turn, are responsible for the innervation of skin, muscles and joints of leg and foot. So if you start to ask where is the sciatic nerve, you can safely skip the area at the back of the thigh from the buttocks, lumbar and to the big toe.
The main symptom signaling about sciatica (so called sciatica) are pain of different intensity. Depending on the cause, they can also be felt as a light tingling, and as attacks of burning pain, not allowing it to move. Usually a pinched sciatic nerve, symptoms of which differ from the ordinary inflammatory process is more severe and sharp pains manifest the strongest algea appearing when moving, physical exercise or just when you try to change your position. Usually pain is present in only one limb, the other only the patient feels weakness or numbness. Often the pain attack is preceded by difficulty of movement in the affected limb, which can also be seen as inflammation of the sciatic nerve. The symptoms often accompanied by pain in the lumbar region.
In addition, the inflammation can signal the following characteristics.
- Violation of the sensitivity in the course of the nerve innervation – typically, this happens where is the sciatic nerve, while on the affected area can be observed as hypersensitivity, and a significant reduction in it. There, where the nerve can be observed burning, tingling, "creepy crawling" or numbness.
- Reduced mobility is also often accompanies this disease. It may affect the knee or ankle joints, separately or together. Also a fairly common complaint in this pathology is the weakness of the muscular apparatus. Patients difficult to withstand the loads that require tension in the muscles on the affected side.
- A pinched sciatic nerve, symptoms of which, in addition to the above symptoms, often cause a change in gait. This is due to the fact that the patient seeks to reduce the burden on the affected side, shifting the center of gravity where there is no pain. Support becomes healthy leg, and the patient tucks. The torso is also deflected in the opposite direction from the affected side.
Causes inflammation and pinched nerve
Sciatic nerve, symptoms and treatment of inflammation which becomes a problem for many, may be affected by several pathologies of the locomotor system, but the most common one is the osteoarthritis. Following this disease doctors-vertebrologists called a herniated disc and piriformis syndrome. In addition, to cause pinching and inflammation, which will be its consequence, can by the following factors:
- trauma of the spine;
- neoplastic processes
- excessive physical activity
- infectious processes.
Another cause of sciatica can be a stressful factor. Muscle tension that occurs at the same time, is able to impinge upon the nerve roots, thereby affecting the sciatic nerve. The symptoms and treatment in this case will be the same as in pathological processes, but the positive results of treatment will appear only after the source of stress is resolved.
Before you begin treatment, you need to make certain that the cause of pain is inflammation of the sciatic nerve. To do this, the neurologist, in addition to the standard survey and examination of the patient, which allow to estimate the extent of destruction, assigns x-rays. This survey allows us to identify bone changes in the body. If this is not enough to understand how to cure the sciatic nerve, may be appointed as an MRI or CT scan which are much more informative research methods. If there is reason to suspect the tumor process, is carried out radioisotope scan of the spine. Especially important this study is for people receiving long-term corticosteroids.
When urgent consultation with a doctor
Most people tend to the last to ignore and postpone visit to the doctor when inflamed sciatic nerve. The symptoms and treatment of this pathology is usually quite typical, and many people prefer to self-medicate. However, if you have the following symptoms, one should immediately consult a neurologist.
- Amid pain syndrome began to rise the temperature.
- On the back appeared swelling or redness of the skin.
- Increased area of the body where there is pain.
- Numbness in the extremities reaches such an intensity that hinders movement.
- Have problems with urination or defecation (incontinence, pain or burning sensation during the act).
Regime in an acute period
In order to cope with possible manifestations and consequences of entrapment, you need competent treatment, which should be comprehensive and include, in addition to drug therapy, izlechenie, massage and physical therapy course. However, until the end of the acute period, which usually is dominated by pain, you must comply with bed rest. It is better if the surface of the mattress is quite hard. Motor activity during this period to reduce. Please note – at this time do not want to use a hot compress as under the action of heat can increase swelling of the tissues, thereby increasing the pressure on the nerve. In some cases, reducing pain allows massage movements with the ice cube in the area of localization of pain or alternating warm and cold lotions.
As a rule, for the treatment of sciatica used drugs from the group of NSAIDs (non-steroidal anti-inflammatory drugs). Their advantage is that they do not cause strong addiction and can be used for a long time, but they have a number of side effects, the most serious can be called a bleeding tendency, abnormalities in the kidneys (swelling), headaches. The most often used “Ketonal” (“Ketoprofen”), “Piroxicam”, “celebrex”, “Diclofenac”. Today the pharmacy network offers a huge selection of such drugs, but do not self-medicate. To treat needs specialist.
In addition to drugs NSAIDs for treating inflammation of the nerve used vitamins (B1, B12, E), muscle relaxants (“Mydocalm”, “Sirdalud”). In severe cases and in severe pain prescribe painkillers (Vicodin) and steroid drugs (“Dexamethasone”, “Prednisone”).
Deciding how to cure the sciatic nerve, the doctor, along with drugs appoint physiotherapy. As a rule, they do not affect the cause of the disease, but help patients significantly reduce pain. In addition, they allow you to work medicines directly to the site of inflammation. Thus, by assigning electrophoresis with antispasmodics, anti-inflammatory drugs, muscle relaxants or vitamins, your doctor significantly speeds recovery of the patient. Excellent results also indicate UHF, magnetic therapy, phonophoresis, paraffin baths and UFO. With these procedures in the affected area, increases circulation, decreases swelling and decreases pain.
The same effect has and massage. Thanks to him, improves nerve conduction, improves blood flow. But to start massages after decrease in acute processes, that is, after I disappear acute pain.
If, after the examination was ascertained from the cause of the disease, is assigned a set of physical therapy. Better if it will be developed for each patient individually. Assign it, and conduct the first classes needs a competent specialist. All exercises are performed at a slow pace and without the stress. In case the exercise causes pain, it is better to waive or reduce the range of motion. In the early days of loading and the amplitude of movements should be minimal, the exercises are performed in bed. At least reduce the intensity of pain increases and the load. However, be aware that there are situations when any load is expressly excluded. This can be, for example, if it is well established that the pathology of the discs became the reason that caused the situation when inflamed sciatic nerve. Gymnastics can enhance the existing protrusion and greatly aggravate the patient's condition.
In order to prevent inflammation or to avoid its recurrence, you need to pay more attention to maintaining the tone of muscles. If you have a sedentary job, take breaks more often, while conducting a little workout. The importance of correct posture and regular strengthening exercises. It is necessary to avoid injuries and hypothermia, limit the heavy lifting and in case of any alarming symptoms, do not delay, turn to the experts. Treat yourself carefully and carefully and then you will forget where is the sciatic nerve.
