Has anyone had their knee start playing tricks on them prior to surgery?

No pain, swelling, instability, nothing. I mean, I haven’t been in the gym or anything physical since the week of Thanksgiving and then I have been sick. Gym and activities are usually the biggest triggers for my knee issues. But still it’s making me reconsider my decision… obviously my arthritis has not just disappeared. But would it make more sense to just live a more sedentary lifestyle and not go under the knife? Hmmm
