The right lower extremity has been sore and uncomfortable, while the left lower extremity is normal, the first thing to consider is whether it is suffering from lumbar disc herniation. A lumbar disc herniation compresses the nerve root of the sciatic nerve in one lower extremity, thus producing soreness, swelling and uncomfortable sensations. If the symptoms of compression and irritation are further aggravated, symptoms such as radiating pain, abnormal sensation and muscle strength loss in the lower extremity along the sciatic nerve can occur. Symptoms can also occur due to the nerve roots in the spinal canal being squeezed as a result of the herniated disc, producing radicular pain or due to local inflammation that irritates the nerve roots. After further compression of the nerve root, it will lead to impaired blood circulation to the nerve root and nerve damage, producing certain symptoms. When there is soreness, swelling and uncomfortable feeling, it only means that the local symptoms are not very serious, and active diagnosis and active treatment should be carried out to prevent further aggravation of the disease. Often, the nerve root compression is too long and the stimulation is too heavy, and irreversible damage to the nerve occurs, and even if the corresponding treatment is carried out, it is impossible to completely restore normal.
