Hello amigos,

My CRPS started in my left thumb and hand and fairly quickly spread up to my elbow. The last three days have been some of my best pain days since the onset but I'm starting to have sensations in my right hand and arm that feel like they're a ramp-up to what I have on the left.

I did have an IV in my right hand just preceding these new sensations. Also worth mentioning is that it's been insanely cold where I live and I'm going outside in subzero temps several times a day and even with the best outerwear the cold reaches my arms and hands.

My questions are: Could this be spread? What should I watch for? Should I notify my doctor? Or at what point should I notify my doctor?
