Bone marrow edema in the area of the ankle may be caused by trauma, or there may be inflammation in the local area, such as osteomyelitis. If the bone marrow edema is caused by trauma, the main thing is rest and treatment. Treatment of the local area can be done with drugs that activate blood circulation and remove blood stasis, such as Yunnan Baiyao aerosol, local spray, and if it is caused by inflammation, timely antibiotics such as cephalosporin are given. Topical magnesium sulfate can also be applied topically to help reduce bone marrow edema. Pay attention to rest and try to avoid exertion and excessive walking, which helps to limit the inflammation. Appropriate nutritional support, more lean meat, milk, eggs and other high-protein foods will help recovery. Attention should also be paid to observe local improvement, and if the inflammation is severe, osteomyelitis requires surgery if necessary.
