It’s not “normal” (and there is no normal) because for your particular knee you are doing way too much and your knee is begging you to stop.I can’t understand why it’s not “normal”
You have never given it a chance to go away. You went back to work extremely early. That takes a major toll on recovery, more for some than others. In addition you insist on doing exercises that are obviously stressful for your knee. And if I remember correctly, early on you were doing a lot around the house, I think I remember you saying you didn’t have much support from your family. I’m so sorry that they were not more helpful so you could rest most of the time you were/are home.I have pain all the time it never went away..
I realize you must work. Please consider that alone your PT. Continuing to do all this extra exercise is obviously not helping. And at 4 months almost all of us are stiff after sitting. At 4 months I was still very uncomfortable sitting with my feet on the floor. And at 4 months we all had that tight band feeling. I still do at almost a year!
Listen to Celle. If you continue to do way more than your knee wants you will continue to have this pain.Never push through the pain. "If it hurts, don't do it." Pain is your knee's warning that you are trying to do too much for it. Ignore that warning and you could set up a chronic inflammation, which will retard your progress.
You can tell yourself you are not overdoing it but your knee is telling you different. If you push the knee, the knee will push back and the knee will always win. The knee is in charge of this recovery, not you, not your PT, not your surgeon.I push through the pain but I don’t over do it.
Robin, we all care about you. We all are so sorry that your recovery is more difficult than most. Please think carefully about all you are doing and slow down. If you don’t you may end up in a worse place than you are now.

Tough couple of days, here’s hoping I sleep tonight and wake up feeling better tomorrow.
