I have learned that soft tissue ailments are rough, they come and go, and they really do linger.
I finished PT, but I am still stretching the quad, hammy, hip and piro formis, and calf muscle - ever since my full knee replacement in Jan 2024 it has been bothersome.
Stretch everyday and just be happy that I walk fine, I golf, I hike, and mostly do whatever I want. But it will mean maintenance forever.
