In medicine, sciatica is a condition, not a diagnosis, because it only indicates that the nerve is being compressed, but does not specify the source of the compression or the mechanism of the disease. There are many causes of sciatica, usually directly related to tissue lesions around the lumbar spine that press on the nerve line, including: lumbar disc herniation, spinal stenosis, spinal subluxation, lumbar spur growth, narrowing of the intervertebral foramen, pear-shaped muscle syndrome, etc. An accurate diagnosis and treatment can only be made after examination and evaluation by a health care provider. Symptoms of sciatica Patients with sciatica usually feel pain in the lower extremities, and the location of the pain depends on the nerve root that is under pressure and is accompanied by a numbing sensation. In severe cases, the lower limb muscles may become weaker, the muscles may atrophy, the skin may feel numb, and the tendon reflexes may decrease. In order to avoid pulling the sciatica nerve to reduce pain, patients often have some special postures to reduce pain, such as preferring to sleep on the non-painful side, bending the leg on the painful side, using the buttocks on the non-painful side when sitting down, shifting the body weight on the non-painful side when standing, and bending the knee joint on the painful side when bending down to pick up things, which will cause scoliosis over time, mostly to the painful side, and will lead to mild muscular atrophy over time. There will be mild muscular atrophy over time. Treatment of sciatica 1.Physical therapy: traction therapy, interference wave electrotherapy, ultrasonic therapy, heat therapy, manual therapy and exercise; 2.Magnesian therapy; 3.Posture correction: to reduce the pressure on the spine to avoid further degeneration and degeneration of the spine; 4.Workplace design: to help maintain good posture and reduce the speed of cervical degeneration; 5.Medication: pain relief, anti-inflammatory drugs and related medications prescribed by a doctor; 6.Surgery: for the painful side of the spine. 6.Surgical treatment: applicable to cases with severe symptoms, please check with the specialist for details. Prevention of sciatica 1. Posture correction. Maintain the normal physiological curvature of the lumbar spine (moderate forward curvature) when sitting and standing, reduce the pressure on the vertebrae and intervertebral discs to avoid aggravation of degeneration, reduce the wearing of high heels, and control body weight; 2. 4. Home treatment: Apply hot compresses 1-3 times a day for 15-20 minutes each time to relieve muscle tension and pain in the lumbar region and reduce pressure on the lumbar spine; 5. Back exercises: Continue to perform targeted back exercises prescribed by the physical therapist until the pain disappears, and continue to practice after recovery.
