How painful is it when doctors remove rods in the bones after fractures heal up?

Hardware removal. Intramedullary rods are used for fracture repair in long bones. Once the bone heals, the rod has no bio mechanical function. On rare occasion, the rod may cause pain, usually by irritating local tissue. The rods can be safely removed. Usually the only significant pain is incisional, and short-lived.
Rod removal. The pain should not be too bad after a rod removal and the recovery is very fast.
