The symptoms of pain on the inner side of the right hip bone may be caused by the following reasons: 1. The most common disease that can cause this symptom is soft tissue injury around the hip joint. The injury often occurs due to sudden violence such as sudden fast running and falling, and may also be caused by heavy physical labor and local soft tissue injury. Patients with this condition may experience pain along with limited movement, and the pain may increase when moving the right hip joint. The pain is usually cured within two weeks by resting and braking and using blood-boosting drugs. 2. Some patients with hip synovitis, whether due to cold or overwork, will experience pain in the medial hip bone. Unlike other diseases, most patients suffering from synovitis will experience localized swelling, which may appear suddenly, and the pain may gradually worsen.
