Hello, I just had a 19 year old broken heal bone fixed and it's doing find, but now my knee and lower knee are in pain and my lower half of my leg is swollen, this goes down through out the night and the pain is gone when I wake up. I been walking for three weeks with out the boot, with the boot on everything was OK. Could it be the tennie shoes I'm wearing (there a good brand), I'm going to buy a different type of shoe tonight - What do you think?
