What causes pain in the inner thigh when moving, and what should be done about it?

Pain in the inner thigh during movement may be caused by muscle strain, adductor muscle inflammation, leg nerve compression, iliacus-psoas muscle group abnormalities, or avascular necrosis of the femoral head. Symptoms can be relieved through daily care, physical therapy, or surgical treatment. If bodily discomfort occurs, prompt medical consultation is recommended.

1. Muscle strain: During exercise or physical activity, the inner thigh muscles may become overstretched or sprained, causing pain. It is advisable to rest the affected area, apply cold compresses to reduce inflammation, use supportive straps for added stability, and gradually perform mild stretching exercises to promote recovery.

2. Adductor muscle inflammation: The adductor muscle group, located on the inner thigh, can cause pain when inflamed. Rest is recommended, along with cold compresses to reduce inflammation. Physical therapy and specific stretching exercises can help relieve tension in the adductor muscles.

3. Leg nerve compression: Nerves in the inner thigh may become compressed—such as in cases of sciatica or other nerve pain—leading to discomfort. Rest and avoiding prolonged periods in the same posture are advised. Physical therapy, nerve decompression exercises, and medication may help alleviate pain caused by nerve compression.

4. Iliacus-psoas muscle group abnormalities: Conditions such as iliacus-psoas muscle inflammation or tightness may lead to pain in the inner thigh. Rest and cold compresses can help reduce inflammation. Stretching and strengthening exercises for the iliacus-psoas muscles, along with physical therapy, may help restore muscular balance.

5. Avascular necrosis of the femoral head: This condition results from insufficient blood supply to the femoral head, leading to bone cell death and structural deterioration. It may cause inner thigh pain, limited hip joint mobility, and difficulty walking. Treatment options include core decompression surgery, in which small holes are drilled into the femoral head to reduce internal pressure, improve blood circulation, relieve pain, and promote healing in the affected area.

In daily life, maintaining proper posture and avoiding prolonged static positions is important. Before exercising, adequate warm-up activities—including stretching—should be performed to reduce the risk of muscle injury.
