One of the questions I got in the Runners Aid Station was: “Do I really need a fracture walking boot?” This is a runner who went to the doctor, and was told, "You have extensor tenosynovitis. The best way to get it to calm down is to remove the inflammation and stop aggravating the tendons." If you get aching pain on the top of your foot, it might be caused by an irritated extensor tendon sheath (which is the little tube around the extensor tendons as it goes out to the toes on the top of the foot). If so, you might be thinking you need something drastic to stop the tendons from moving so it can calm down. Do I need a fracture walking boot for extensor tenosynovitis? Well, that's what we're talking about today, on the Doc On The Run podcast.
