Bone Fiber Dysplasia does not affect walking if it is mild, but if the bone destruction is severe it affects walking.
Fibrodysplasia ossificans has no symptoms in the early stages if it is mild and does not affect walking.
If it is severe, there will be bone pain, localized deformity of bones, localized swelling, and in severe cases, pathological fracture will occur. This can cause lameness, difficulty walking, and inability to walk if a fracture occurs. If pain occurs to limit walking, reduce weight bearing to avoid pathological fracture.
Therefore, if there is no symptom of abnormal bone fiber proliferation disease does not affect walking, when there is pain, swelling means more serious, need to go to the hospital for further treatment.
