Can my foot injury heal while I am sick?

I just got off a webcam call in the Injured Runners Aid Station. The runner who called me, had some down with a cold. He had been sick for a few days. He wasn't running. He was curious about whether or not his injury was going to actually get worse while he was ill. Because he knows that when he's sick, his immune system is working really hard to try to fight the infection. And your immune system can't do everything all at once. If you have an injury, it is widely accepted that the illness is going to slow down your potential ability to rebuild tissue and repair damaged tissue, whether a metatarsal stress fracture or an Achilles tendon injury. Can my foot injury heal while I'm sick? Well, that's a great question, and that's what we're talking about today on the Doc On The Run podcast.
