As you detected by feeling my tendons, I already had damage to them before I started my hiking vacation. Pain had flared up in that ankle while I was ‘training’ to get in shape before my vacation. By hiking I added to the damage and definitely caused the stress fracture in my heel. We loved the trails and the people in Virginia despite my pain! Thanks to you and your staff for your fine care (and those nice metatarsal pads).Christine M.
