It is not recommended to eat roast duck in the early stage of fracture because it is a kind of food that is easily inflammable because it is greasy. In case of local swelling and pain in the early stage of fracture, or in case of open fracture with wound, if you eat roast duck, which is easy to get hot, in the first few days after the surgery, it is likely to induce more serious swelling and pain, and it may also induce inflammation and infection in the local wound. However, 1-2 weeks after the fracture, if the local swelling or wound is completely stable and there is no infection, eating some roast duck is not a problem and will not have much effect on the fracture or the wound.
