I knew something was wrong when my tongue inexplicably began tingling.
It was a sudden, prickly sensation – almost like I had pins and needles on my tongue. (This is a sensation I get in my feet when I’ve had them in a certain position for too long and I need to get the blood flowing properly again. A quick Google search taught me that just about anyone can experience this, so odds are you already know what I’m talking about.) And it lingered for a solid 20 minutes, making my entire mouth feel as though it was simultaneously numb and on fire from the unrelenting feeling.
This is my new(ish) low symptom: tongue tingling.
And I hate it.

It only seems to occur when my blood sugar hits the 50s or 60s, which doesn’t happen too often. But when it does, it hits me so abruptly that it catches me off guard every time. It’s an unpredictable phenomenon – usually, my first sign of a low blood sugar is feeling shaky/sweaty/dizzy. Once I feel those initial signs of a low, I’m pretty good about being quick to do something about it by grabbing something sugary to eat…and when tingly tongue strikes, it can make the entire eating experience unpleasant because it almost feels like I’m having an allergic reaction to my low snack. And it lasts longer than it takes for my Dexcom to pick up on a recovering low blood sugar.
I’ve genuinely been worried that I was having an anaphylactic reaction in addition to a hypoglycemic event, prompting me on more than one occasion to run over to the closest mirror to check and make sure that my mouth and face aren’t swelling up or turning red. Let me tell you, it’s enough to deal with the low blood sugar sensation – feeling like I’m having an allergic reaction on top of that makes a normally easy-to-deal-with low that much, well, suckier, to be blunt about it.
I classify it as only sorta, kinda new because I’ve dealt with something similar in the past. In fact, roughly 4 years ago, I wrote about “a fuzzy towel tongue” feeling that I experienced after a low blood sugar. It’s funny that I wrote about it because I think at the time, I only ever felt that a handful of times, and the symptom seemed to disappear. But now, it’s apparently back with a vengeance, as the tingling feels much worse now than the numbness I’d felt a few years back.
At least I know that I’m not alone. I’ve talked to my fellow T1D mother about this and she’s also experienced it, in addition to the folks I’d interacted with in the context of my original post on the matter. It might not be fun, but there’s (quite literally) strength in numbers.
