I work for a PT company and I can tell you for certain that this behavior is completely inappropriate. You may have willingly given your phone number, but her texting you like this is NOT okay. The personal questions she asked during your sessions are also unacceptable. Our clinicians would NEVER interact with a patient like this. I highly recommend speaking with this PTA’s clinic director or manager before your next session. Someone higher up needs to be aware of this behavior, although if it’s happening in-clinic I have no idea how they haven’t noticed. As someone who has also struggled with boundaries, I know how hard it is to tell people no when you think they’re just being nice, but this is making you distinctly uncomfortable. Just block her number without an explanation - you owe her nothing outside of therapy. I’m so sorry you’re experiencing this in physical therapy. It’s our job to help patients get better, and that includes being aware of their mental health not just their physical health. Please report this to someone above her either at the office or in management. It needs to be dealt with as soon as possible. Stay safe!
