Thanks for posting your query
You had fracture
in your left arm five years back & at that time some surgery done with screws and after that immobilization in plaster cast for 5 months.
Now after 5 years you had severe pain in arm
at the fractured site.
So an x-ray of right arm is needed to see the condition & quality of bone. fracture site , implant condition.
So you have to visit an orthopaedic surgeon
for exam. of arm & treatment plan acc. to that.
