I have a question regarding mast cell disorders. After 12wks on the safe diet and almost two weeks of "perfect" poop, I have reacted to something that has makes me fear I've been set back six months (overreacting I am sure, but this is fear speaking). I think it may have been some bitters I added to my water kefir on the weekend (I added quite a bit, but probably only two teaspoons over two drinks) and the next day I had complete D. The following day was almost normal again, but the day after complete mush again. I'm feeling pretty devastated after feeling like I was finally turning a corner since being in somewhat of a flare since March.
Anyway, kind of related to this is the fact I have to get my vaccine and after finally feeling ok with the idea of it, I am now feeling nervous again. A blood test two weeks ago showed I have low platelets (129) and also low white blood cell count. This left me very worried, as I also had low platelets on two occasions last year (145 in Oct 20 and 137 in Nov 20) and have never had them (that I know of) prior to this, therefore prior to the onset of MC. Following from this, I was filling in the questionnaire to book in my Pfizer shot and it asked "Do you have a previous confirmed medical history of heparin induced thrombocytopenia (HIT)?" which worries me, as although I haven't had this, I do currently (or at least two weeks ago) have slight thrombocytopenia. It also asked "Do you have a mast cell disorder?" which reminded me of stuff I had read here and made me Google it and read all about it and worry even more, as it can also cause cytopenias and other symptoms similar to MC.
Sooooo.....something obviously triggered me over the weekend. It caused D then mush and I also had a sore throat on Mon-Wed, which I thought may be a cold coming on as my twins are sick, but now I am wondering if it is a histamine reaction, as I have been a little itchy in the arms too. The itchy arms have happened to me before throughout all this and I just thought it was part of MC, but now I am scared it might be a mast cell disorder and that makes me worried I might have a reaction to the shot, worst case anaphylaxis. So, what is the difference between a full blown mast cell disorder and what we experience with MC? Should I be worried about getting the shot? What about this platelet issue? I did think that perhaps it was related to taking Loperamide daily, but now I am not so sure.
Thanks for reading my anxious thoughts.
