You probably know somebody who suffers from plantar fasciitis -- that's a tiny tear (a micro tear) in the plantar fascia that strikes runners and other athletes all the time. But the difference between plantar fasciitis and a plantar fascia rupture is huge in terms of pain and recovery time. The plantar fascia rupture is far less common. Runner's World explains that plantar fascia rupture is associated with a vigorous foot plant and that "in three words, it really hurts."
That explains Peyton Manning's injury and career-worst performance (5-for-20 for 35 yards, no TDs and four interceptions) against the Chiefs. He sure looked like it "really hurt" and vigorous foot planting is what Manning has done better than anybody over his long career. Runner's World says the treatment for a plantar fascia rupture is "non-operative and healing the tissue back to full strength takes 12 or more weeks." Whether Manning's injury is closer to a micro tear or a rupture will be watched carefully by Broncos fans.The BEST SALES on Amazon NOW ]
