What is the reason for the pain in the inner thigh root muscle

The pain in the inner thigh root muscles may be related to muscle strains, hip synovitis, inguinal hernia, femoral head necrosis, lumbar disc herniation, and other reasons. It is recommended to seek medical examination in a timely manner, clarify the cause, and receive targeted treatment.

1. Muscle Strain

Intense exercise or improper posture may cause excessive pulling of the inner thigh muscles, resulting in partial tearing of muscle fibers. Typical manifestations include local tenderness, swelling, and restricted movement, with increased pain during coughing or compression. During the acute phase, exercise should be stopped and ice should be applied. In the later stage, hot compress and moderate stretching can be used to help with recovery.

2. Hip synovitis

Hip synovitis can stimulate peripheral nerves and cause radiating pain, often accompanied by hip stiffness and bouncing sounds during movement. Excessive walking and rheumatic diseases can both trigger and require diagnosis through ultrasound or magnetic resonance imaging. Treatment includes joint immobilization, anti-inflammatory drugs, and physical therapy.

3. Inguinal hernia

When the contents of the abdominal cavity protrude through the inguinal canal, it may compress the obturator nerve and cause referred pain. The pain is obvious when standing or exerting force on the abdomen, and can be relieved when lying flat. Palpation may reveal a lump, which requires hernia repair surgery for treatment. Delaying treatment may lead to the risk of intestinal impaction.

4. Femoral head necrosis

Long term alcohol abuse or hormone use may disrupt the blood supply to the femoral head. Early symptoms include dull pain in the groin area, followed by limping and joint movement disorders in the later stages. The X-ray shows changes in bone density, which require decompression surgery or joint replacement treatment. Delayed treatment may lead to disability.

5. Lumbar disc herniation

When the nerve roots of the 4-5 segments of the lumbar spine are compressed, pain can radiate along the obturator nerve to the inner thigh. Often accompanied by lower back pain and limited straight leg elevation, CT examination can clearly determine the degree of protrusion. Mild protrusion can be treated with traction and medication, while severe cases require intervertebral foramen endoscopic surgery.

Daily attention should be paid to avoiding prolonged sitting and sudden twisting movements, warming up adequately before exercise, controlling weight, and reducing joint burden. If the pain persists for more than three days or is accompanied by fever or numbness symptoms, immediate medical attention is required. You can try low impact exercises such as swimming and cycling to strengthen muscles, supplement calcium and vitamin D to promote bone health, and use a pillow under the knee to relieve nerve pressure during sleep.
