Thanks for writing in.
Seems she has undergone the surgery under general anesthesia
. The drugs & the endotracheal tube used during general anesthesia causes such dryness, pain in throat and some times cough
too. It usually resolves within a day. She will be alright once she is allowed to take liquid fluids initially. Follow your doctors advise as she is in immediate post-operative period.
/ pain is no way related to the removal of rod or anti-biotic impregnated cement.
Wish her a good recovery,
