I have been suffering with an all over body itch which causes nerve pain as well. I also suffer from chronic nausea. My doctor diagnosed me with mast cell activation disorder. He put me on droxia. It only help with occasional shin pain. I want to stop taking it but doctor does not agree. I have an itch specialist that wants me to be on Zeljanz. I would rather try this, but doc treating mast cell problem will not prescribe until I try droxia or another drug first. I want to stop the droxia. What should I Do?
