but know I will need pain control when I begin outpatient PT in a few days.
I’m very sorry about that itching, but I have no advice for it.
However I do have advice about your statement I quoted.
It is not necessary for PT to hurt, so you don’t need pain medication for it. You need pain medication in general because you’ve just had a major traumatic surgery, but not to take care of extra pain due to PT.
As far as pain during PT, it is your body telling you that you are doing things that are not in your new knee’s best interest.
If PT does cause pain, you are getting the wrong kind of PT and should either speak up, or go somewhere else, or do your own at home.
All we hear is PT is going to hurt, and for most people it does. That doesn’t make it correct. Most of us are being mislead by our surgeons and PTs that we have to work hard at this recovery. They don’t take into account that our body needs to heal.
Keep in mind, it’s not exercising that gets our range of motion back, it’s Time:
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. Exercise as in strength training is counter-productive and in the early weeks does more harm than good. Normal activity is the key to success.
