[|Human|] hello my name is lennon and i had a compound fracture about 1 year and a half to 2 years ago, they left a pin inside. i have recently in the last 2 days have much pain and my wrist swells underneath the wrist making it hard to move my fingers and wrist. do you know what that can be from?
[|AI|]  Hello, I read your question and understood your concern. Since you had a compound fracture the most probable diagnosis is a post-traumatic arthritis which is that the joints involved in the fractures start to wear the cartilage surface and rub bone on bone. This is outcome in 20% of these fractures. The second option is that the pin left inside has migrated (moved) and causes pain and inflammation and need to remove it. A simple x-ray of the wrist would clarify this situation. Hope I have answered your query. Let me know if I can assist you further.
