Dear Swimtime,
I hope your son does not have CRPS and there is something else found with a more direct and successful treatment protocol. That said, no one is questioning my diagnosis and I do not nor have I ever had allodynia. Temp changes are variable. At first it was hot most of the time, now after a year it's cold some of the time. I do have apopping in my ankle sometimes, but I usually describe it as crunching. Point is, to meet criteria symptoms can still vary. I'm sure you know this with all your research, but I thought it might help to hear it from someone living it too. You sound like a wonderful, resourceful, supportive Mom. All the best ~mama mac
