The following steps are usually taken to recover from a strain on the knee joint: First, avoid getting cold in the knee joint, as cold will slow down the blood circulation in the location of the strain and lead to the accumulation of inflammatory metabolites, which will further aggravate the symptoms and condition of the strain. Second, use a warm water bag to apply hot compresses 3-5 times a day for 20-30 minutes to increase blood circulation and promote the absorption of inflammatory metabolites, so that the symptoms of the strain and the condition can be significantly restored. Third, avoid frequent knee flexion and extension activities, such as cycling, mountain climbing, stair climbing, as well as strenuous exercise and long-distance walking, which can lead to further aggravation of the position of the knee strain, resulting in a gradual increase in the condition. Fourth, when sitting, try to choose a high chair, not a low bench, because when sitting on a low bench, the knee joint will be in a state of flexion, which will lead to further aggravation of the strain, and cause blood circulation to slow down, leading to aggravation of the disease. In addition, you can take oral Chinese medicine to activate blood circulation, reduce swelling and pain, such as blood circulation and pain capsules, which can effectively increase blood circulation and play a role in activating blood, reducing swelling and relieving pain.
