Need to explain therapeutic treatment.

I have the titanium rod placed on my right hand shaft bone.It has been placed for more than 4 years.I am very eager to know weather this thing should be removed immidiately or it should not be removed[no side effects].I have done all the xrays and all were good.Its seems that broken bone is already got fixed and supporting rods are useless.My age is 23 currently. People are advising that there is no need to remove it, perhaps it would invite operation cost etc. I don’t have any complications at work.But still i fell, there is lack of confidence from my side during gym and other excercises. What would you suggest to me. If removing the rod is an only option left and its too urgent then i am ready to undergo for a surgery. Please also let me know,if some wrong could happen if i don’t get it removed, as i am not too old. Please suggest me Thanks for your time
