Plantar fasciitis is another very common injury Cox has sustained several times. The inflammation of a thick band of tissue connecting the heel bone and the toes will cause pain in the heel or arch of the foot. This injury can be self-diagnosed – it usually hurts the worst in the morning after you wake up and make a few steps. Depending on how serious the injury is, you may need physical therapy, shoe inserts, steroid injections, or even surgery.
