I appreciate this article. I've had the opposite experience with surgeries - I recovered faster than expected - but I've had this experience with other medical issues. My brain injuries, for example.
I thought my first concussion would heal in a week or two since everyone said it would. I was shocked when it took more than a year to recover from it, and some of my symptoms remain 8 years later. It doesn't help that I've had multiple concussions since then, but still. In the past, I've also pushed myself too hard, too soon, because I thought my body was better.
Hope you get back to feeling like yourself again soon.
