Greater trochanteric bursitis (GTB), also known as hip bursitis, is a condition characterized by inflammation of the bursa located near the greater trochanter of the femur (the bony prominence on the outside of the hip). The bursa is a small fluid-filled sac that acts as a cushion and reduces friction between tendons, muscles, and bones in the hip joint.

Causes:

1. Repetitive stress or overuse of the hip joint, such as from running, walking, or cycling.

2. Trauma or injury to the hip, such as a fall or direct impact.

3. Poor posture or biomechanics that put excessive strain on the hip.

4. Muscular imbalances or weakness in the hip or surrounding muscles.

5. Certain medical conditions, such as rheumatoid arthritis or gout, can increase the risk of developing bursitis.

Symptoms:

1. Pain and tenderness on the outside of the hip, specifically over the greater trochanter.

2. Pain that may radiate down the thigh or buttock.

3. Increased pain with activities that involve hip movement, such as walking, climbing stairs, or lying on the affected side.

4. Stiffness or limited range of motion in the hip joint.

5. Swelling or warmth in the affected area.

6. Pain that worsens at night, particularly when lying on the affected side.

Treatment options:

1. Rest: Avoiding activities that aggravate the symptoms and giving the hip time to heal.

2. Ice and heat therapy: Applying ice packs or heat packs to the affected area to reduce pain and inflammation.

3. Nonsteroidal anti-inflammatory drugs (NSAIDs): Over-the-counter medications like ibuprofen or naproxen can help alleviate pain and reduce inflammation.

4. Physical therapy: Exercises to strengthen the hip muscles and improve flexibility, as well as manual therapy techniques, can be beneficial.

5. Corticosteroid injections: In some cases, a corticosteroid injection may be recommended to reduce inflammation and relieve pain.

6. Assistive devices: Using crutches or a cane can help reduce pressure on the affected hip during the healing process.

7. Modification of activities: Making modifications to activities or using proper techniques to avoid excessive strain on the hip.

8. If conservative measures fail, surgery may be considered in severe cases, but it is usually a last resort.

It's important to consult with a healthcare professional for an accurate diagnosis and to discuss the most appropriate treatment plan for your specific condition.
