What a question.

There are so many different sorts and locations for the pain and they tend to move around especially over the long term. Arthritis pain morphs into RSD pain and slowly goes away only to come back as arthritis pain or something else. I've had polka dot pain so have come to believe almost anything is possible.

The RSD does have a couple components which might didtinguish it from other pain. The areas affected sometimes feel like dead meat. It usually doesn't hurt at this time but sometimes it feels like an anchor or a weigh depending from me. My pain is best described as a crushing/ hot pain like a bus with hot tires is parked on it. But this pain can become a small component of other less similar pain.

Everything just keeps changing and I'm so pessimistic when I hurt and sometimes revert to my natural optimism when I don't. Triggers keep changing but it seems I'm always doing less and less and this really hurts.
