I have my first pt Appointment soon

I have my pt booked in two days. Now I’m almost 5 days after OP. At the moment I barely manage to washroom and move. Standing up or moving,doing any kinds of moment is unbearably painfull. I still manage to keep my leg straight and small movements even if it’s hurts like crazy.
I was wondering should I cancel the appointment and wait for few more days? I feel like it’s gonna be impossible to make the journey and honestly I don’t see any way I can learn any kind of new movement at the moment.
