Symptoms of synovitis of the femoral joint mainly include pain, swelling and limitation of activities. 1. Pain: The pain is often more obvious after hip joint activities or after catching cold or overwork. 2. Swelling: synovitis of the femoral head is often accompanied by fluid accumulation, and localized swelling may occur if there is a lot of fluid accumulation, which is usually not very obvious in the hip joint, but can be seen through physical examination if there is too much fluid accumulation leading to severe swelling. 3. Restriction of activity: if the pain of synovitis is obvious or there is more fluid, there may be restriction of activity in the hip joint. These are the common symptoms of synovitis, but its diagnosis and treatment need to be further confirmed through the examination of the cause of the disease.
