You will be fine doing your own PT at home, at your own pace. Gentle bends, comfortable walks, and doing things in your normal day as able, is really all the “PT” you need. I call this “natural PT.”
Regaining our ROM is more about Time than repetitions of a list of exercises.
Time to recover.
Time for pain and swelling to settle.
Time to heal.
Our range of motion is right there all
along just waiting for that to happen so it can show itself.
In the general run of things, it doesn't need to be fought for, worked hard for or worried about. It will happen. Normal activity is the key to success.
