I’m in the process of reviewing the information you have posted on Mast Cell disorders and it does make so much sense. Before we figured out my son’s food allergies (biggest culprit I believe being dairy) he would wake nightly with horribly itchy back, wheezing, and nose running like a faucet at night and daytime asthma symptoms. I think his allergies, combined with possible mast cell issues were creating a perfect storm for asthma. Once we removed dairy, his asthma likewise has been all but eliminated. I’m pursuing your zyrtec/zantac test for myself for brain fog issues. I saw where you also mention keeping a food diary. I’d like to second the idea that, in addition to taking histamine-reducing drugs, folks do pursue food allergy testing as they may be initially triggering the histamine-production that can then get out of control when a mast cell disorder is underlying the whole process. At least, that’s my layman’s take on it. Correct me where I’m wrong !
But be sure to pay attention to your own instincts regarding allergies and to find a good doctor to do the allergy testing. It may have been a fluke but when my son’s allergy doctor found he tested negative for a dairy allergy, then when we had him tested 4 months later by a different doctor (and in the interim he was hospitalize with a pretty serious asthma attack) and he tested positive for dairy, it did make me wonder. And, as I say, removing dairy all but eliminated his asthma symptoms. In hindsight, it did make me question the wisdom of having an asthma doctor test for an allergy that could pretty much eliminate his asthma - and the need for the services of an asthma doctor. May be a good idea to have an impartial third-party test for any food allergies.
Would like to hear from any other folks on here who could also add asthma to their list of issues.
