Osteoarthritis: This is the most common cause of hip pain in adults, especially in those over 40. The wear and tear of the joint cartilage leads to pain, stiffness, and limited mobility, which aligns with the typical presentation of hip pain in a 47-year-old.

Trochanteric Bursitis: Inflammation of the bursa over the trochanter, often caused by repetitive friction or direct trauma, leading to pain on the outer aspect of the hip.
Piriformis Syndrome: Compression of the sciatic nerve by the piriformis muscle, causing pain, numbness, and tingling in the buttock and leg.
Hip Labral Tear: A tear in the labrum, the cartilage that surrounds the socket of the hip joint, often due to trauma, sports injuries, or degenerative changes, leading to hip pain and limited mobility.

Avascular Necrosis (AVN) of the Femoral Head: A condition where the blood supply to the femoral head is disrupted, leading to necrosis of the bone tissue. It's crucial to diagnose early to prevent collapse of the femoral head.
Septic Arthritis: A bacterial infection within the joint space, which is a medical emergency requiring prompt antibiotic treatment to prevent joint destruction.
Stress Fracture: A small crack in the bone, often due to overuse or repetitive stress, which can lead to complete fracture if not addressed.

Synovial Chondromatosis: A rare condition characterized by the growth of cartilage in the synovium of the joint, leading to joint pain, swelling, and limited mobility.
Paget's Disease of Bone: A chronic condition that can result in enlarged and misshapen bones due to abnormal bone destruction and regrowth, occasionally affecting the hip.
Bone Tumors: Both benign (e.g., osteoid osteoma) and malignant (e.g., osteosarcoma) tumors can cause hip pain, though they are much less common than other causes.
