Broken Ankle pain that wont go away

In late february i was sleddin with some buddies and we went off of a jump and of course i was in the front and was pushed out by the force and both of them landed on me while i also landed on my feet. my ankle snapped and my foot was facing the opposite direction. i ended up with a plate and five screws put in my ankle. all of it was removed in late may. i guess my question is that 6 months after some time i get an excruciating pain like i broke it all over again for no reason. sometimes it does it when i get up in the morning and sometimes it does right in the middle of me walking. im confused as to what it is.
