Thanks much Bruce. That makes sense.  

Thank you too Peter.

Both of you are really well versed in this and I am finding out just how important it is.  

Now that I have 'some kind' of diagnostic confirmation that doctors who are not familiar with mast cell disease can see in a study, all my specialists are taking an interest and contacting my mast cell doctor for guidance with my health care.  Kind of sad, but also progress!

Hope you both are doing well.  Appreciate your posts!
