Pain on the left outer side of the thigh

There are many reasons for thigh pain, such as excessive fatigue, strenuous exercise, local soft tissue damage caused by trauma, local muscle and bone tumor diseases, such as atypical radiating pain caused by femoral head necrosis, lumbar disc herniation, lateral femoral cutaneous neuritis, etc. So what are the causes of pain on the left side of the thigh, and how to relieve the pain symptoms? Let us understand it in detail.

reason

Lateral femoral cutaneous neuritis: The lateral femoral cutaneous nerve is derived from the 2nd to 3rd lumbar nerves, passes through the lateral edge of the psoas major muscle, obliquely passes through the iliacus muscle, along the pelvis through the deep surface of the inguinal ligament, and passes through the fascia lata 10 cm below the anterior superior iliac spine to the skin of the thigh. This disease may occur if the lateral femoral cutaneous nerve is affected by compression, trauma or infection during its course. Such as spinal deformity, hypertrophic spondylitis, spina bifida, lumbar spondylosis, intervertebral disc herniation, lumbar myositis, pelvic inflammatory disease, neurosyphilis, appendicitis, pregnancy, heavy labor, pelvic tumors, alcohol poisoning, inguinal hernia and sequelae of herpes zoster, etc., can induce this disease. Cold and humidity are also common causes of this disease.

Lateral femoral cutaneous nerve entrapment syndrome:

1. The lateral femoral cutaneous nerve is angled where it exits the pelvis and enters the thigh. In addition, due to anatomical variations, when the limbs are moved or the body position is improper, the nerve is subjected to continuous traction, friction, and compression, etc., causing local tissue edema, scar formation, and thickening of the muscle fascia sheath, resulting in nerve compression.

2. Pelvic fractures, tumors, foreign bodies, and plaster compress the lateral femoral cutaneous nerve, causing entrapment.

3. The nerves are stimulated when the iliac bone is removed during surgery, or local scar adhesions compress the nerves.

4. This syndrome may be caused by hematoma in the iliopsoas fascia caused by trauma or in patients with hemophilia.

Mitigation methods

(1) Physical therapy: including massage, electrotherapy, audio-frequency electrotherapy, heat therapy, magnetic therapy, and iontophoresis after ultraviolet irradiation.

(2) Drug treatment.

(3)Surgical treatment.
