Wont speak for Quintana who but for me- yes at sit bone and yes- pain can come down your leg, calf and foot If you train on this injury long enough. You can develop scar tissue on sciatic nerve right at site where sit bone and 3 tendons attach if you are lucky like I was! :( . My pain began to travel down my leg and foot. During my 4 hour surgery to reattach tendons- 2 hours was cleaning up all the scar tissue. I feel like a miracle after years of suffering. I read all the threads and learned on ST when first diagnosed years ago as it was hard anywhere else to find info on.
