I just wanted to write because I've gone thru the infection thing and believe me you should know if it gets infected!!
Mine got infected before the staples were removed and I thought the bad pain was just from the staples pulling in my cast. The pain was so bad, percocet didn't touch it Finally I couldn't stand it any longer and went back to the doc. They took off my cast and immediately saw the infection. They put me in the hospital right then, The next morning I had to go back in surgery for the OS to do a debribement? or something like that. I stayed in the hospital 4 days for this. I never want to go thru that again.
Just be careful and if something doesn't feel right, be sure and call you doc. Better to be safe than sorry.
Hope all goes well with you.
