Man;
Congrats on your new shiny BHR, great to hear from another Brooks patient. I was out after 2 nights each time as well, despite the great care, I was ready to go for sure. I hated those noisy compression stocking devices-- for me the worst part.
I would really caution you to try and be as patient as humanly possible, I know how hard that can be, but it will really pay off. You being a triathelete I'm guessing the no running for a year is going to be tough for you, but it is a "marathon" versus a sprint and with care and feeding this hip should last a very long time. I'm doing incredibly well after 14 months on #1 and approaching 10 months on the second.
Also, don't skip the exercises, they are critically important to do as long as they recommend, even though you are far ahead of many, try to keep them going.
Thanks for sharing and best regards going forward.
Dan
