Bone marrow edema usually recovers well after 3 to 4 weeks and can be treated with active rest, medication and closed treatment. 1. Active rest: first of all, we should pay attention to rest, keep warm to avoid getting cold, avoid a position for a long time, and avoid repeating a certain kind of movement for a long time, because these bad habits will easily lead to synovial inflammation, which will lead to bone marrow edema. Usually after 3 to 4 weeks, you can recover better. 2. Medication: Some anti-inflammatory and analgesic drugs such as Loxoprofen sodium can be used to effectively inhibit inflammation and reduce exudation. 3. Closure therapy: when elevating the affected limbs to avoid excessive sagging, local closure therapy can also be carried out, and the use of tretinoin injection can effectively inhibit inflammation. Specific diagnosis and treatment should be carried out under the guidance of physicians.
