Suggest Remedy For Pain

I had a surgery on june 4th 2010, in which they were suppose to remove the screw

frm my previous ACL recunstruction i had in 2006 due to reinjury. But the screw

broke in process of taking out, and part of it is still left in my bone. There

is still pain. My question is, Will this pain go away? any idea how long will it

take? worst comes worst can dis be permanent? Is dis negligence in any way that

my doc couldn't do the job right? Thank you.
