Windyshores, that’s quite a story. I’ve always had LBP - always did, and now I take a beta blocker to regulate superventricular tachycardia, which lowers it further. Never occurred to me that it might play a role in this business. OTOH, I’ve been taking it since 2015 and always had eGFRs in the 70s and 80s until now. So probably not a factor.
