Hi Seaglass,
Keeping your positive attitude is a big help on so many levels. And there is reason to hold onto hope, 80% of people with CRPS improve over time according to Cleveland Clinic's Dr. Michael Stanton-Hicks who does a lot of the CRPS research.
It is important to hang onto your recovery and continued care as well, like a bulldog sometimes. Identifying and treating any underlying pain contributors can make a huge difference in your outcome. Please push for any workup that you need such as Nerve Conduction Study or imaging.
I hope that you are able to get what you need soon. Keep doing the things you are able to without flare and take exceptional care of yourself. It is hard in the beginning but there is life after CRPS and treatments that help. It does take some time to find the ones that work for YOU. So keep hanging in there and come back to let us know how you're doing.
Sending healing thoughts,
