What causes pain in the outer thigh bone?
I have been experiencing persistent pain in the outer side of my thigh bone recently, especially after walking a lot or exercising, with the pain becoming more noticeable. Sometimes I also feel a slight numbness in the outer side of my thigh. What could be causing this? Why does pain occur in the outer side of the thigh bone?

Pain in the outer thigh bone can be caused by several possible factors:
1. Muscle or tendon strain: Muscles in the outer thigh, such as the iliotibial band or tensor fasciae latae, may become injured due to overuse, improper exercise techniques, or sudden increases in physical activity, resulting in pain.
2. Femoral stress fracture: Common among athletes, especially runners. Prolonged repetitive stress can lead to tiny cracks in the femur, causing pain.
3. Iliotibial band syndrome: A common issue among runners and cyclists. The iliotibial band rubs against the lateral femoral condyle, causing inflammation and pain.
4. Hip joint problems: Conditions such as hip arthritis or avascular necrosis of the femoral head may also cause pain in the outer thigh area.
5. Osteoporosis: More common in elderly individuals, decreased bone density can present as pain in the outer thigh.
6. Calcium deficiency: This condition may lead to reduced bone density and subsequent pain.
If the pain persists or becomes severe, it is recommended to seek medical examination at a hospital immediately.
