Hey) If you're on antidepressants or thinking about starting them - maybe stick around for this one. It might save you a confusing trip to the doctor. And yeah - medical talk ahead, so be warned.

So two days ago, after a long day of nothing of significance, I wanted to have a nighttime snack and couldn't open my mouth all the way. Without sharp pain in my jaw that is. I didn't think much of it honestly. Life is full of random pains that come and go and you just technically accept that your body is a mystery machine that sometimes throws error codes for no reason.

Yesterday morning it actually felt better and I thought - cool, yeah, as I thought, one of those things, moving on. And then the evening came and my mouth just… didn't open. Like, I physically could not open my jaw past like a quarter inch without this sharp, electric kind of pain shooting through the joint. Yogurt from the flattest spoon I own it is. Talking was uncomfortable. And I had to explain to insurance that I needed to expedite my visit for the next day. I had to take ibuprofen at 2 am just to relax enough to drift off.

Today I went to a neurologist. Described everything. She felt my jaw. And she just said, "Yeah. That's a muscle spasm, possible bruxism. It's a known side effect of escitalopram."

Bruxism - for those lucky enough to not know the word - is when you grind or clench your teeth. Sometimes while you sleep, sometimes during the day without even realizing it. Your jaw muscles just go into overdrive, and you have to "breathe manually" to keep the jaws separated.

And here's the thing that I hate the most about the human body: SSRIs like escitalopram work by increasing serotonin levels in your brain. Great for anxiety. Great for depression. Like thumbs up, but serotonin also suppresses dopamine in certain pathways. And dopamine is... I always thought about it as you know, a love hormone, motherly love, the mesocorticolimbic circuit, and such. Well, also it's the thing that makes edging "press that little button in our brain that says, 'Okay, you're happy now'" (sorry, couldn't resist). Same with street drugs - they either force the brain to overproduce it or block reuptake or just flood the system with it. Schizophrenia, Parkinson's, OCD - like all the arrows point at it being... purely a psychology-regulating thing.

But the thing that was new to me is that it keeps your involuntary movements in check. Like blood vessels contracting, kidney secretion, guts pushing food along, and apparently how hard your jaw clenches.

The neurologist said it's not rare either. It's documented across almost all SSRIs - escitalopram, fluoxetine, sertraline, the whole squad. And yet somehow nobody warned me about this when I started the medication. Not even the little paper pamphlet that lists 200 side effects in a font size designed for ants.

So now we figure out what to do. Options on the table are adjusting the dose, possibly adding buspirone, which apparently helps with this, or switching meds entirely. Fun. Oh how much I love rearranging the chemical furniture in my brain like it's an IKEA apartment.

But here's why I'm writing this. If you're taking an SSRI and you suddenly start waking up with jaw pain, headaches, or tooth sensitivity - don't just chalk it up to stress. Talk to your doctor. Don't ignore it like I almost did. It might literally be your medication making you clench your teeth hard enough to damage them - in your sleep - while you have zero awareness of it happening.

Oh and don't stop your meds on your own - that's a whole different can of worms you don't want to open. Love, fam.
