    How do i get my doctor to pay attention to my case and be less scattered and more responsible ?

    I found an amazing immunologist and mast cell specialist. I thought "since my current me/cfs specialist is too scattered to help me well, this doctor should suffice, and maybe she can lead a bit more in treating my case rather than me having to do a lot of the steering". Well, our first visit...

    Problems with Mast Cell stabilizers

    So I'm at my wit's end a bit this evening. I'm currently on a plan from my MCAS doctor to take Mast Cell stabilisers in the hope it calms my symptoms, but I've just tried a new one (Ketotifen) and I'm reacting badly to it, and I'm wondering what to do.
