Feeling off: body tremors, heart palpitations, weakness, and anxiety...

Hi everyone on this sub, I wanted to reach out because I have a few questions for you all 😛
I was wondering if thyroid issues could actually trigger these kinds of sensations, or if my heart is more likely to be the culprit here. Has anyone else gone through something similar to what I'm experiencing?
I'm 21 years old and have always been perfectly healthy up until now, without any prior medical history.
Lately, I've been dealing with extrasystoles, and I get these strange fluttering sensations throughout my body—mostly concentrated on the right side of my neck—but honestly, it feels like the entire right side of my body is just overly sensitive.
Other than that, I generally feel fine and don't have many other symptoms, though I do get hit with bouts of discomfort and restlessness from time to time. Regarding my thyroid, my hormone levels and antibodies look okay, but my initial TSH reading was 7.8, which later came down to 4.7, and my ultrasound looked normal.
My blood pressure is totally fine.
My resting pulse is steady at about 75 bpm, and it goes up to around 120 or 130 when I'm exercising.

I'm currently waiting on the results from a Holter monitor I started wearing yesterday, after which I'll be seeing a cardiologist to address the extrasystoles. However, is there a chance that my heart is actually healthy and these symptoms are being caused by something else entirely?

Everything really kicked off about three weeks ago when I had this sudden, overwhelming moment of weakness, almost like I was going to collapse. I couldn't even stay on my feet; I had to sit down immediately, and for about thirty seconds, my right arm went completely numb. It passed fairly quickly and I felt a bit better, but I was absolutely terrified. That was the first time I ended up in the ER, but they checked me out and sent me home saying everything seemed fine!
The second time I ended up in the emergency room was just a few days ago, again because of that intense restlessness, discomfort, and the feeling that I might pass out. This time, they gave me these diagnoses:
ventricular extrasystole?
subclinical hypothyroidism
suspected thyroiditis

They also prescribed some medication for me:
Conor 1.25mg (though my doctor later switched it to Byol Cor 1.25mg)
I haven't been super consistent with taking it; I usually only take it when I feel a heavy surge of extrasystoles.
I also take Normabel as needed.
Whenever I take those two, the extrasystoles seem to disappear completely. 😵

It could be MS, some kind of nerve impingement, or maybe just something else entirely

Based on everything I’ve been feeling lately and after doing a bit of digging online, it really seems like what I'm dealing with is anxiety.

I was just about to type that out for you!

It could potentially be a thyroid issue. 🤔
Before you even got that first TSH reading—and honestly, you didn't mention what your actual lab numbers were—were you dealing with a lot of stress? Or any other symptoms? Did they run tests for T4 or T3 as well?
Also, is there any history of thyroid problems in your family, like with your mom or dad?
I’m asking because of this specific part:

I can't tell if they're just being extra cautious with the diagnosis.

My mom has been dealing with some kidney issues lately,

You missed including the reference ranges for the TSH—every lab in the States uses different benchmarks—but based on how you pulled those two specific results and those suspected diagnoses together in your opening post, I’m guessing it’s running high. If that's the case, given everything else you're feeling, it might be worth asking your primary care doctor for a referral to an endocrinologist. That way, you can get the full battery of tests done and finally get some clarity on what's actually causing this and whether you even need treatment at all.
The thyroid affects just about everything in the body, and it can definitely trigger various issues, including those heart palpitations and that restless, uneasy sensation you described. Then again, those sensations could just be your reaction to the ventricular extrasystoles themselves, which can feel pretty unsettling to some people. As for what triggers extrasystoles, there are plenty of culprits, like, for instance, .
Good luck.

Anxiety and

You don't just pop CONCOR whenever you feel like it. It’s about consistency.

Anxiety is such a beast. It could totally be a thyroid issue, but honestly, I’ve dealt with all those exact same symptoms just from being anxious myself.

I wanted to share a quick update since it’s been quite a while since I last posted. Everything seems to have cleared up on its own without any formal medical treatments or prescriptions about six months after everything first started. Looking back, I think that one instance where I had some mild carbon monoxide poisoning from a faulty car engine really threw my thyroid out of whack for a bit, and that, combined with a heavy dose of both mental and physical stress, really triggered some anxiety. My TSH levels were running high for a while, but during every checkup over the last six months, they slowly drifted back down, and now everything is finally sitting right within the normal range.

All my other test results came back perfectly fine, and honestly, I’m not experiencing any symptoms at all anymore. I’ve just been being a little more mindful about what I eat—mostly just cutting out sodas and keeping things simple. If anyone else out there is dealing with similar symptoms, please don't panic; it's really not as scary as it feels initially. Just try to keep your stress levels in check, cut out the caffeine, ditch the junk food entirely, and you’ll likely find yourself feeling much better soon.🙂

Oh, and if you’re struggling to relax or having a hard time falling asleep, you could try taking some Normadel to calm your nerves, though it's probably best to use that sparingly as well. 🙂
