When there is fluid in the hip joint, we should pay attention to the following aspects: 1. Braking and resting should be carried out, and we should not continue to stand, walk or move around on the ground. If too much activity causes excessive load on the hip joint, it will easily lead to an increase in the amount of fluid, which will cause damage to the hip joint itself, thus causing irreversible damage. 2. A clear diagnosis should be made, and it is best to go to the hospital for treatment to find out the cause of the fluid and take the appropriate treatment. Common causes include hip synovitis, reactive arthritis of the hip joint, as well as hip joint injury and strain, all of which can lead to effusion, and can be relieved by local symptomatic treatment. For a small amount of fluid in the hip joint, it usually only produces discomfort, soreness and swelling of the hip joint, and does not produce obvious dysfunction and pain symptoms, so you can take oral fenbid and celecoxib for anti-inflammatory and analgesic treatment, and at the same time, you can apply heat and baking electricity and other physical treatments locally. It is recommended that the patient should have a clear diagnosis before carrying out the corresponding treatment, so as to avoid slow recovery or even injury due to incorrect treatment. For example, if the hip joint becomes infected, there will be local redness, swelling, heat and pain, and septic fluid will be produced, in which case the effect of conservative treatment is often unsatisfactory, and antibiotic treatment or even surgical treatment will be adopted.
