Thanks for your query.
Old age is a cause for delayed healing of wounds.
But according to your words the leg is swollen and the wound is painful and leaking.Is she having fever too?Is pus coming out ? There are chances that she developed chronic osteomyelitis
. You must get it checked up from your doctor and get a X Ray done.
Apply antiseptics like providone iodine
locally on the wound. Keep it clean and prevent from getting soiled.
Taking Vit C will help in healing process.
For pain give her analgesic
Hope this helps.
Update here how she stays.
