Thigh pain

Introduction The disease may have different complications depending on the cause of leg pain. For example, some patients start with only leg pain, and gradually one side of the lower extremity is weak, limp, followed by paraplegia, and the prognosis of malignant leg pain is mostly Poor, if it is caused by metastatic cancer, the prognosis is worse, which may lead to more complications.

Cause

(1) Fatigue: During the day, the amount of exercise in the leg is too large or excessively exerted, resulting in fatigue. The state of nighttime muscle tension is not improved, too much metabolites are not metabolized in time, and its stimulation can cause calf cramps.

(2) Cold: When sleeping at night, cold feet and legs can cause leg muscle spasms.

(3) Hypocalcemia: When hypocalcemia occurs in the body, the threshold of excitability of the neuromuscular junction is lowered, and the stimulation intensity below the normal condition can excite the nerve muscles, thus easily causing abnormal contraction, causing calf cramps . This situation is more common in pregnant women and the elderly who are deficient in calcium.

(4) Blood flow factors: For patients with leg varicose veins or deep vein thrombosis, if a certain posture is maintained for a long time while sleeping, the veins of the legs are compressed, the reflux is blocked, and the blood flow stagnates. When the blood stasis reaches a certain level, It can cause paralysis of the leg muscles.

Electromyography mammography X-ray examination CT examination

1, lumbar X-ray film

Simple X-ray film can not directly reflect the presence of disc herniation, but the degenerative changes such as narrowing of intervertebral space and vertebral edge hyperplasia are sometimes seen on X-ray films. It is an indirect suggestion. Some patients may have spinal deviation and spinal side. Convex. In addition, X-ray film can be found with or without bone disease, tumors and other bone diseases, with important differential diagnosis.

2, CT examination

It can clearly show the location, size, shape and nerve root and dural sac of the disc herniation. It can also show the laminar and ligamentum hypertrophy, small joint hypertrophy, spinal canal and lateral recess stenosis. In other cases, it has a great diagnostic value for this disease and has been widely used.

Differential diagnosis

First, the patient should be asked in detail about the medical history, including the patient's age, gender and occupational status, the cause and onset of the disease, the nature and location of the pain, the length of the disease, and the physical condition of the past.

Secondly, for spinal examination, you can press the look, touch, sputum, movement, volume and nervous system examination, and proceed one by one in order to avoid omission. When making the examination, pay attention to moving the patient as little as possible or changing the position. Specific to patients with low back pain, can be divided into position, sitting position, supine position, prone position and other positions to check patients, but also should be combined with nervous system examination.

Finally, according to the specific circumstances, the corresponding joint and internal organs should be examined to rule out other diseases.
