Pounding pulse wakeup

Every now and again (maybe once every week or so) I wake up with my pulse pounding loudly in my ears. Usually my mouth is dry. I can hardly move at first, and sometimes I've just had a vivid dream. I usually feel hot, but that's normal on waking (still get hot flushes).

It is definitely not a panic attack as my breathing is normal and there's no feeling of fear. Even though loud, my pulse feels normal too, though possibly slightly fast, (I'm never awake enough to be able to time it before the noise fades). The other week the pounding was so loud that it was impossible to hear outside sounds at all.

As soon as I wake the noise dies down very quickly - probably less than half a minute.

Any ideas on what might be the cause? I think I had it occasionally before being diagnosed with Hashimoto's, but it was never very loud.

Interested in responses to this. My daughter has something very similar happen, but only when she takes a nap during the day...regardless of time of day or length of nap. I suspect she is still undertreated based on her fT4/fT3.

So it could be a hypo symptom? I often feel dreadful if I go off to sleep very heavily during the day (doesn't often happen). Like a zombie when I wake up, takes up to an hour or more to be able to function again.

I don’t know if it is, but I have been suspicious that it is. I’m hoping someone will have experience that clearly pointed that way or not

I had this problem when my TSH was suppressed and my dose wasn't high enough. I have been taking magnesium glycate and that has also also helped. The pounding in my ears has stopped and I sleep better. When my dose was wrong I was waking up with adrenaline rush and sometimes hypoglycemia

Thank you, that is very helpful

I tried to look it up and a couple of links said it was a hypERthyroid symptom!

I don't get it. Unless, as with heart or eye problems, it can be caused by either hyper or hypo, but for different reasons.

I am certain it isn't hyper because I still have several hypo symptoms. As they think I am still overmedicated (below range TSH and fairly high T4) that is a bit of a concern!

Yes this is the problem docs always think you are hyper. I ended up in hospital heart rate 170. My T4 was only 15.1 TSH 0.4 so they said oh yes you're hyper reduce your dose! I asked them to test T3 they refused. The ambulance driver was the only one that spoke any sense he said I think you need to up your dose.

Of course they could be right that I'm overmedicated, but I don't think so. I was going to use the pounding in the ears as evidence I was still undermedicated, but dare not now!
