I remember finally at just over 3 months pain went away and I could finally sleep. Awesome, but then a few weeks later I had setback with pain returning.
I was in tears. My therapist told me to hang in that it happens. I also checked with another friend who had a TKR and he said that he had a setback at one point during recovery too and got through it. So I kept on and with 4 months I was doing outstanding. Today 1 1/2 years later my knee is awesome. I hope you are having the same therapist every time. I feel that that constant one on one has been key for me! My therapist in addition to exercises, icing, elevation, he used dry needling, muscle stimulator, deep tissue massage, cupping and taping of the knee. Call and talk with your therapist about what’s going on, hopefully they can help. Best of luck
