if the chicken bone has passed through your throat then it will not get stuck any where else.. because throat it the narrowest part of the git..also when chicken bone will go into stomach it will surly get digested, stomach contains acid will strong enough to digest even small iron nails.
now you need to get some investigation done. with the history you have given it is tough to tell your diagnosis. but it may even be a stone in the ureter
. what i would suggest is visit a hospital with all the investigations you have done from the time bone got stuck in you throat. then they will do step by step investigation to find out what is causing the pain
