Hi kijo!
From what your therapist told you, I would be a little wary of her. I do not agree with her advice for you. Some folks will differ in this opinion, but ice it the worst thing you can put on RSD/CRPS. It is a well-known fact that it is bad and can cause spread. And pushing yourself until you swell and cause pain doesn't sound too good either.
You need to find a doctor and a therapist who is very familiar with RSD/CRPS and treating patients with it. I personally did not benefit from physical therapy, it actually caused more problems for me. There are many on here that have benefited from it and hopefully they will chime in on what to look for in a good therapist.
Good luck with your appointment tomorrow.
