ok My names Alan and im 24 years old, Now in 2002 i was struck by a van and the guy was doing 50 mph and i was walking! now i had my tibia and fibia in my left leg broken right in half and they had to incert a long thick titanium alloy rod with a seurgical steel plate and 11 screws directly into my bones, i also shattered my left elbow, cracked my shaulder blade to where i received a hairline fracture in it , but i also ended up with my head busted open on my forhead and you could litterally see my skull!! ya i didnt enjoy that all too much, and now i get to be fortunate enough to walk around with all this hardware in me , so now that you know why im writing let me ask you this? i move furniture in an American freight warehouse all day long for like 10 hours and we dont have heat in there so its only about 12 degrees in there and im constantly lifting furniture well over 100 pounds all day but ive been doing it seince i was able to walk again. now getting to the point i just recently within the last few days started having an extremely difficult time menuvering at work and home, I have severe pain in the leg that my surgeury was done on and it kind of feels as though its going up the bone but it could be the muscle to i have no idea but this is the worse it has been in 7 years and my ankle locks up on me and i cant hold my own weight on it, and also while im sleeping my arms hurt so bad that i automatticly wake up and notice my hands are swollen, in pain and numb so whats going on here ?can you help me understand? is the titanium alloy rod,surgical steel plate, or screws dangerous or damaging my leg? could they be cancerous to the bone or marrow? the doctor told me before the opperation that if anything -my leg would be 110 % better for about 7 years but then i may want to concider having it removed because it could quite possibly be cancerous they had only used that type of rod on 12 other people at the time is this true? and what should i do about my leggs,arms, and hands as far as the pain gose? could it just be repetitave movements in the cold temp?
