Running is not recommended for synovitis of the hip joint, and should be judged according to the condition. In patients with synovitis of the hip joint, the synovial membrane in the hip joint is hyperplastic and hypertrophied, and secretes fluid, which can cause swelling and pain in the hip joint, limiting the movement of the hip joint, not being able to do squatting, and the pain is aggravated after walking a long distance, so running is not recommended in this case. Running may stimulate the synovial membrane to secrete more fluid, resulting in increased joint pain. Therefore, when hip synovitis occurs, you need to rest and apply blood-activating and pain-relieving drugs, such as synovitis granules, or oral non-steroidal anti-inflammatory drugs, such as ibuprofen extended-release tablets, and you can also take deep heat therapy. Hip synovitis when the pain disappears, joint mobility recovery, MRI examination of the effusion disappeared can be moderate running. The specific situation needs to consult the doctor to make specific judgment.
