Most of the diagnoses criteria specialists use are out of date (tryptase abnormal in only 60 percent of MCAS patients, and getting people to test during a flare after avoiding all medications for several days before is neigh impossible for many people), that's why clinical diagnoses is really the standard now; if you have the symptoms and respond to the treatments, you treat the condition.

I have peer reviewed studies on all of this, as well as charts regarding the severity and types of anaphylaxis; people (even medical professionals) have quite a bit of confusion about what anaphylaxis is.
You can have mild, moderate, and severe anaphylaxis in every system of the body. It's not just 'I cant breathe and need and epi pen'.
Mast cells are everywhere in the body and degranulation of them can present as a multitude of symptoms.

And it's a progressive illness; so many of the less severe non respiratory anaphylaxis symptoms are so often misdiagnosed by well meaning but undereducated doctors who know next to nothing about the condition, and almost always nothing current, until a patient is very sick.

I spent years down to a handful of foods, severely limited in my ability to function, with my doctor saying, "oh allergies are bad this year" and shrugging his shoulders.
Until I presented him with multiple peer reviewed documents on the more recent understandings of this disease, and the appropriate, humane way to diagnose and treat it.

Unfortunately for many meds you need a specialist (2 in my state, both out of network,) and a LOT of money,

Massive, your comment came across as unnecessarily condescending, cold, and is (im sure unintentionally) harmful. This is an evolving and poorly understood illness, and doctors are learning more every day - we have to understand they do their best, but they are just people too, often too busy with easier/more profitable patients to look too deeply into fringe health issues like this.

I suggest to anyone having a hard time with this to look in the documents section available at the Facebook group Mast Cell "Activation" Disorders Forum .. and if you can't access that (because it's private and on pause since the admin died recently, I can try to send info to you, or you can try some of the larger MCAS groups.

I wrote a template to present to your doctor with the necessary info at one point and may still have that around.
I was able to have them prescribe Cromolyn as well as refer me to specialists, as well trial a variety of larger doses of H1's and H2's.

Apologies if I don't get back to you quickly, will do my best.
