TRS I feel your pain.....
Did the same thing to my ankle sliding into second base playing softball in 1982.
Slid wrong and when my right foot hit the bag it folded under and stretched the outside ligament so bad and so quickly that it tore off a bone chip where it attaches to the bone.
Then it got misdiagnosed as "just a bad sprain." Two months later and I still couldn't walk on it without a severe limp so back I went (to a different doc) and after new x-rays found out about the bone chip.
Four weeks of physical therapy later and I was back to about 85% and there I remain forever with my ankle permanantly swollen.
I did get back into jogging about 2 years after and didn't do too badly. Usually just enough residual pain to remind me it was there though so I switched to lower impact exercises when those new fangled fancy treadmills and elipticals came out.
Got a permanant 10% VA disability for it. Not worth it though, and I'm sure it will affect me more later as I get older.
