@windyshores maybe you need to consider a new PT? If all they do is massage without giving you exercises at home and in office you won’t get better. I have similar symptoms due to OA and stenosis of C-spine. My home exercise program keeps my upper back a den neck in check.
If you watch TV, sit at a device typing or just reading a book can set off your shoulders and neck from keeping your head still. I get up every 30 minutes and break the cycle.
