1, consider lateral femoral cutaneous neuritis.
Lateral femoral cutaneous neuritis, also known as allodynia, is the most common cutaneous neuritis in clinic, and it is a disease with abnormal skin sensation on the lateral thigh.
Etiology:
(1) The lateral femoral cutaneous nerve was compressed.
When the lateral femoral cutaneous nerve goes down to the groin through the lateral margin of psoas major, it runs at a large angle and passes through the inguinal fascia, so it is vulnerable to injury, and its compression position is usually at the anterior superior iliac spine. The common causes are: spinal deformity, hypertrophic spondylitis, spina bifida, lumbosacral sacralization, pregnancy, pelvic tumor, retroperitoneal tumor, inguinal hernia, disc herniation and so on. , can cause this disease.
(2) Trauma or infection
Such as: lumbar myositis, pelvic inflammatory disease, neurosyphilis, appendicitis, herpes zoster sequelae, etc. can induce this disease.
(3) Others
For example, diabetic neuropathy is easy to involve this nerve. Drug poisoning, alcoholism, cold and dampness are the common causes of this disease, and the causes of injury in some patients are unknown.
Main symptoms:
Numbness, ant walking, tingling, burning, chills and heaviness are the most common.
Incidence population:
Most of them are obese young and middle-aged men.
2. Consider lateral femoral cutaneous nerve entrapment syndrome.
Lateral femoral cutaneous nerve entrapment syndrome refers to nerve dysfunction caused by lateral femoral cutaneous nerve entrapment in its path.
Etiology:
(1) The lateral femoral cutaneous nerve has an angle at the pelvic joint. Combined with anatomical variation, when the limbs are not in the correct position, the nerve is continuously pulled, rubbed and squeezed. , leading to local tissue edema, scar formation, myofascial sheath thickening and nerve compression.
(2) Pelvic fracture, tumor, foreign body and plaster compress the lateral femoral cutaneous nerve, resulting in entrapment.
(3) Stimulating nerves when cutting ilium, or compressing nerves by local scar adhesion.
(4) Intrafascial hematoma of iliopsoas caused by trauma or hemophilia can cause this feature.
Main symptoms:
The affected hip has tingling, aching or tearing pain, thigh string pain, but all of them exceed the knee, and there are symptoms of numbness and pain in the lower limbs. The pain is deep, the area is vague, and there is no obvious distribution boundary. Bending, sitting up, leg lifting and other activities are limited.
Incidence population:
Most patients have a history of waist and hip flash injury and sprain, especially women.
3, consider it is myofibrositis.
Myofibrositis refers to lumbar myofibrositis, which refers to a series of clinical symptoms caused by edema, exudation and fibrous lesions in the myofascia and muscle tissue of the waist due to cold, humidity and chronic strain.
Etiology:
(1) is affected by humid and cold climate. Wet and cold can make the muscles and blood vessels of the waist contract, and ischemia and edema cause local fibrous serosity to ooze, eventually forming fibrositis.
(2) chronic strain. Fibrosis changes occur after the back muscles and fascia are damaged, which makes the soft tissue in a state of high tension. Thus, a slight tearing injury occurs, and finally the fibrous tissue increases and contracts, squeezing local capillaries and peripheral nerves, causing pain.
(3) others. Such as viral infection, rheumatic muscle allergy and so on. It's all motivation.
Main symptoms:
The main manifestation is diffuse dull pain in the back, especially above the bilateral psoas major and iliac crest (outside the thigh root).
(1) local pain, chills, numbness, muscle spasm, dyskinesia.
(2) There is obvious localized tenderness.
(3) Pain disappeared after external application of Yaotong Fuzheng ointment.
(4) Pain often occurs in the early morning, and is relieved or disappeared after exercise and hot compress.
Incidence population:
Middle-aged and elderly people are the most common among all people.
4. Consider sciatica.
The sciatica of most patients is secondary to the pathological changes of the local and surrounding structures of sciatic nerve, which is called secondary sciatica. A few are primary, that is, sciatica.
Main symptoms:
Sciatic neuralgia is mostly unilateral, and the pain is mainly confined to the distribution area of sciatic nerve, mostly persistent pain. The sciatic nerve trunk has obvious tenderness, and the gastrocnemius muscle has tenderness. Achilles tendon reflex is weakened or disappeared, and stimulation can enhance knee reflex.
Incidence population:
Most people are over 40.
5. Stretching exercises to relieve pain at the root of thigh.
1. Face the floor, straighten your elbows and put your hands on the floor.
2. Stand up with the knees of one leg bent, and keep the other leg with the inside up and put it straight on the floor.
3. Stretch your legs as far as possible, and keep the root of your thigh as close to the floor as possible.
4. The upper body rotates slightly in the opposite direction of the leg extension. Finally, keep the most comfortable posture.
5. practice alternately left and right.
