Possible causes of pain on the outer side of the left thigh and hip bone may include the following:
1. Muscle or tendon injury: Overexertion, sudden vigorous activity, or improper posture may cause strain or sprain of the muscles or tendons on the outer thigh, leading to pain.
2. Iliotibial band syndrome: Common among runners and cyclists, this condition occurs when the iliotibial band excessively rubs against the lateral femoral condyle, causing inflammation and pain.
3. Sciatica: Compression or inflammation of the sciatic nerve can cause radiating pain from the buttocks down to the calf. The outer thigh and hip region may also be affected.
4. Hip joint problems: Conditions such as hip arthritis, femoroacetabular impingement, and avascular necrosis of the femoral head can cause hip pain that may radiate to the outer thigh.
5. Lumbar disc herniation: When the intervertebral disc in the lower spine protrudes posteriorly, it may compress nerve roots, causing pain and numbness in the lower limbs. This pain may radiate to the buttocks, posterior thigh, lateral aspect of the lower leg, and the sole of the foot.
6. Trauma: Incidents such as car accidents or falls may result in fractures or muscle injuries around the hip area, causing pain.
7. Inflammation: For example, synovitis, an inflammatory reaction of the synovial membrane caused by various factors, may lead to symptoms such as joint swelling and pain.
