hi Carolina Rose,

Can't say if it's CRPS or not but it is certainly a circulatory symptom. Sounds like your circulation is impaired by swelling, then you swell more and it goes from there. Try elevation and some Epsom bath soaks to get the swelling down, gentle movement with ankle rotations and toe curls and if you can tolerate it light compression to help venous return.

Hang in there!
Sending Healing Love,
