Suggest Treatment For Itching In The Throat

Hi., over 13 yrs ago I swallowed a chicken bone and it scratched my throat. Did not know it til I coughed up blood later after supper. I still have problems with my throat occasionally when coughing a lot it causes me to get some blood in mucus or eating rough foods will scratch my original scratch. Right now I have a cold so have that irritation. Any natural remedies I need to be doing? Thanks ! I am 68.
