all of the histamine

I have an appointment to establish care with an allergist today. The plan is to get allergy testing done and then re-initiate allergy shots. I had a truncated course of shots back during medical school when it became impossible to mesh the schedule of the shots (weekly and then monthly) with the schedule of clerkships (all over the fucking place, changing from week to week). I think I had maybe a two year stretch of them? Optimistically, three at the most. The usual course is five years, I think.

So I want to start getting them again because they did make my allergic rhinitis symptoms so much better. It’s a self-imposed problem, of course. I’m somewhat allergic to cats, but I’ve always had cats. And I anticipate that I will keep having cats in the house. I’m also allergic to dogs, and everyone I care about in my life right now has dogs. So… Yeah…

In any event, in anticipation of the appointment and allergy testing today, I’ve been off cetirizine (Zyrtec) for five days now. And IT. HAS. BEEN. FUCKING. MISERABLE. My original allergist in Dallas advised me to take it daily, not so much for allergies, but for my dermatographia (aka skin writing). Basically, minor trauma/pressure (i.e. scratching, poking, nudging OR hell, too much heat or too much cold) to my skin causes a histamine response, leading to hives along the trauma. It’s called skin writing because you can literally write out words and my histamine response will follow.

This is not my skin. From Healthline.com.

Not only does it lead to unsightly welts, EVERYTHING IS FUCKING ITCHY. It’s torture. I’d rather be in pain than be itchy like this. I try to refrain from scratching–it only makes it worse seeing as the scratching causes more hives causes more itching causes more…–but there’s only so much a person can take before the claws come out. There is a small line of petechiae (from broken capillaries) along my right inner arm from a self-attack in my sleep last night.

I can’t fucking wait to be back on Zyrtec. Being off of it has left me irritated (literally and figuratively), grumpy, sleep-deprived, distracted, and, of course, itchy. Medicine is the goddamn best–I will fight you.


Edit @ 2:41p

I ended up having a blood test done instead of skin testing. The allergist tested my dermatographia, took one look at the response, and was like “yeah, that’s going to be too hard to interpret.” I said that I didn’t care how the allergy testing got done as long as it was done today, so she sent me to the lab. She mentioned that you didn’t need to be off Zyrtec for the blood test.

WISH SOMEONE HAD TOLD ME THAT WHEN I MADE THE APPOINTMENT.

I totally would have opted for the blood test straight off the bat and avoided the last five miserable days. But I suppose this is something that the appointment schedulers aren’t trained in.
