Thanks for writing to us.
In the area of fracture
which has been fixed by an implant like IM rod, arthritic changes do develop leading to a constant pain and swelling. The best way is to get the rod removed under a local anaesthesia. It is a minor surgery. otherwise she can take pain killers and do a hot fomentation for relief.
I hope this information has been both informative and helpful for you.
