Back in 1989, I crushed my left heel bone, by jumping down bout 5ft from a boat, that was dry docked, onto a very hard surface. Yup, had been drinking. Tried to get up and walk. Uhhh NO....Went to the hospital, X rays Etc.. Yup crushed Calcainious ??? bone. No cast for that injury, has to heal on its own. Thought I'd be ok in a few weeks....WRONG. Was on crutches for 9 months. But I did start back to driving to my business after a few weeks. Pretty tough with manual trans. LOL... I remember going to my Fathers Funeral at Arlington N.C. on crutches...:(:(
