Knee joint effusion can be combined with baking electrotherapy.
If you are young, you can take western medicine to pump fluid and pressurize it, and use a certain amount of antibiotics and sodium hyaluronate needles for lubrication to control your illness. Physical therapy techniques of traditional Chinese medicine can also be used, such as hot compress, drug fumigation, infrared rays and so on.
Generally, you can wear knee pads to keep warm and pressurize.
If you don't have a lot of fluid, you don't need to rest your legs. However, if there is a lot of effusion, it is recommended to exercise less, reduce the load-bearing and flexion and extension of the knee, raise the legs, promote blood circulation, and be conducive to the absorption of joint effusion. At the same time, exercise quadriceps femoris to shift a little negative focus.
