Can a blister on the big toe cause peroneal tendinitis?

I just got a great question from somebody who said he went rock climbing over the weekend, and he got a huge blister on his big toe from his climbing shoes. He didn't really complain that much about the blister, in fact, he'd even been running. But then he said he was getting peroneal tendonitis. He was having this pain on the outside of the ankle where the peroneal tendons go down around the back of the fibula bone. He wanted to know if it was somehow related to the blister on the big toe. Can a blister on the big toe caused peroneal tendonitis? Well, that's what we're talking about today on the Doc On The Run podcast.
