If you’ve read above you will see I have contributed to this thread. Had both of mine done 3 months apart and, like you, when the nerve block wore off things got a little dicey. The ice machine was my best friend throughout the recovery. I wanted to name it in my will. Really the recovery will be challenging but if you get a good PT and stick with it you will be riding again in a few months. The range of motion is what takes time and can be pretty painful getting it back. It will be two years this February since my first replacement and I am completely satisfied with the results. I didn’t really struggle riding before but everything else was tough and painful. Stairs were awful but now a breeze. I hope you power through the recovery and enjoy the benefits of your new knee. Good luck
