Common causes of pain in the right hip include inflamed tendons, trochanteric bursitis and arthritis, such as osteoarthritis and rheumatoid arthritis, according to Healthline. The most common cause of the pain when it is not chronic is inflamed tendons, which are often due to exercise and go away on their own.
Osteoarthritis occurs when the cartilage that surrounds the bones in the hip joints breaks down, causing the bones to crush other bones, explains Cleveland Clinic. Patients with osteoarthritis experience pain when the bones rub against each other, which becomes more severe over time. Factors that contribute to osteoarthritis include old age, a dislocated hip, genetic defects and diabetes.
Rheumatoid arthritis is an autoimmune disease that affects the joints and their surrounding tissues, according to MedlinePlus. The cause of rheumatoid arthritis is unknown, but factors such as hormone changes, gender and infection contribute to its development. Because the disease affects the joints, patients typically experience symptoms such as joint pain and stiffness. Although rheumatoid arthritis typically affects joints on both sides of the body, it is possible that only the right hip joint is affected.
Trochanteric bursitis occurs when the bursa outside of the hip becomes inflamed, causing hip pain, notes Cleveland Clinic. Patients with trochanteric bursitis usually experience pain on the outside of the hip that gets worse during activities such as standing up from a seated position or walking up stairs. The condition develops after an injury, over-exercise, incorrect posture and other reasons, including diseases such as rheumatoid arthritis and gout.
