Over the past few months I have developed several symptoms outside of my CRPS that my doctors can't yet explain.

-Random hives on my face. They don't seem to connect with anything.
-Random nausea/vomiting. I literally ate the same meal on two different days with proper food storage and one day I was fine and the next day I threw up. A week before that I had 2 glasses of wine with plenty of food and water, which normally wouldn't be an issue. The next day I threw up 6 times. I will be fine for days at a time and then all of the sudden I'm puking.
-Skin rashes with materials that I used to be perfectly fine with.
-Intolerance of beans, which I used to eat ALL. THE. TIME.
-Feeling like I'm falling down while I'm sitting perfectly still. Not exactly vertigo/dizziness. It's like the feeling you get when you accidentally lean too far back in a chair.
-Extremely dry sinuses to the point of bloody mucus (never been a nosebleed person before).

The doctors ran a bunch of tests (blood panel, thyroid, lime disease, RA factor) and they all came back negative. Am I the only one who has experienced this? Could it be connected with CRPS? Anybody have any hints in the right direction?

Any advice would be such a relief.
