Long time no post here. Glad to see most of the regulars are still active, especially OM.

Not about me, but my 59yo climbing mentor and half time partner apparently strained his piriformis muscle about 9 months ago. Its still a major issue as made obvious to me this past weekend when we hiked up to Yosemite Falls and climbed the 2 pitch Lost Arrow Spire route and did the Tyrolean. That's about 8 miles of hiking over 2 days along with the climbing. By the time we got back home he could barely walk up the stairs to his apartment. Anybody have any experience with this kind of injury? The man has larger Yosemite plans, and at a minimum I need to make a decision as to if I stay on this train if he can't get this problem under control. He has gone to various professionals about the injury.
