@fourof5zs Hi ZeeGee, I too have had the CMC arthroplasty with tightrope on my right hand - was scheduled for the left until Covid-19 hit - now on indefinite hold. I too have had trouble reaching health care providers because of changing work sites, restrictions, etc. I second Bill's suggestion that you try again to reach the therapist for a Telehealth session. If they don't respond, try through the surgeon. Many are in transition and working through setting up secure remote sites, etc.
Hang in there and do your exercises faithfully and I think you'll be happy with the results. My friend and I each had ours done 2 years ago, in different places and with different docs, and we are very pleased with the pain relief and usability - but we didn't get quite as much strength as we hoped.
