What could be the reason for a woman experiencing pain in her right thigh?

Right thigh pain in women may be caused by intense exercise, trauma, muscle strain, hip arthritis, lumbar disc herniation, and other reasons.

1. Intense Exercise

Sudden vigorous leg activity without prior exercise habits may lead to excessive lactic acid buildup in the muscles, resulting in thigh pain. It is recommended to keep the area warm and apply heat therapy and massage to the leg to promote symptom relief.

2. Trauma

Strong impact to the thigh area may cause injury to muscles or soft tissues, leading to discomfort such as swelling, redness, and pain. Applying a warm towel for local heat therapy can help improve blood circulation and alleviate symptoms.

3. Muscle Strain

Excessive activity or high-intensity use of the right leg muscles, or maintaining static postures for prolonged periods, may result in sustained muscle tension. This can trigger localized aseptic inflammation, eventually developing into muscle strain and causing pain in the right thigh. Adequate rest is advised. Physical therapies such as ultrasound or infrared radiation, administered under the guidance of a qualified physician, can improve local blood flow and relieve symptoms.

4. Hip Arthritis

In patients with hip arthritis, pathological changes in the hip joint may irritate the obturator nerve or cause joint wear, narrowing the joint space and stimulating nerve endings. This leads to pain in the hip and thigh, possibly accompanied by aching and heaviness. Medications such as glucosamine sulfate tablets, chondroitin sulfate tablets, or glucosamine indomethacin enteric-coated tablets may be used as directed by a physician to enhance joint cell metabolism and inhibit cartilage degradation.

5. Lumbar Disc Herniation

Structural changes in the intervertebral disc—such as the nucleus pulposus and annulus fibrosus—can cause the nucleus pulposus to protrude through a torn annulus fibrosus, resulting in lumbar disc herniation. The protruding tissue may compress the cauda equina or spinal nerves, causing radiating pain that spreads from the lower back to the buttocks, the posterior-lateral aspect of the thigh, the lower leg, and even down to the heel. This may lead to symptoms such as right thigh pain and numbness. Strict bed rest is required. Under professional medical supervision, traction therapy may help retract the protruding tissue, reducing irritation and compression on the nerve roots and alleviating symptoms.

It is recommended to seek timely medical evaluation at a hospital for a thorough examination. Once the underlying cause is identified, targeted treatment should be carried out under a doctor’s guidance. Avoid intense physical activity during treatment to prevent further injury, worsening of the condition, and negative impacts on therapeutic outcomes.
