I understand where you are, Conner is getting to that point, but no muscles tears (yet). He doesn't have corns, but has an old racing injury that healed badly, and now a frozen toe on that foot. The opposite shoulder now has ligament/nerve damage from the years of adjusting his gait for the injured foot, and he now has problems on the two remaining feet (arthritis and a flat foot). He sees a chiropractor every 4-6 weeks which really helps him get back "in line", or as much as he possibly can. Laser treatments seems to help as well.
