Hello~Chest pains, no matter what the cause, can indeed be scary. Sometimes they are muscular, but that type usually hurts when touch certain areas that are hurting, and also, are usually confined to just one spot and not spread over the entire area. Have you been checked for costochondritis, it can mimic heart attack pain, but it is muscular, it means inflammation in the ribs and rib cage area. I would certainly ask about this. Here is a link to some info about, it is from a reputable site: https://www.mayoclinic.org/diseases-conditions/costochondritis/symptoms-causes/syc-20371175
As to going to the ER, I believe that if these symptoms are new, and enough to bother you, then yes, I would certainly go, it is better to be safe than sorry. I am sorry you are getting so many conflicting diagnosis, I would imagine, the doctors are not use to someone young like you having issues, but sadly, it can happen, although rarely.
I hope you feel better soon and that the physicians will be able to get to the root of the cause.
This sounds like a concerning bit of symptoms. Honestly you may need a stress test and echo to be safe. You should absolutely get this re-evaluated.
This arm numbness, is it worse on the side of your arm with your thumb or the side with the pinky? Or is it perhaps the entire arm?
Can you also elaborate on what exactly you mean by “intermittent” chest pain in as much detail as possible?
Do you have any sudden death of heart problems in the family that you know of?
What sort of doctor looked at your ekg? A cardiologist? Do you happen to have a copy you can upload into a drive link?
What is your ethnic background? Try to be detailed as possible as it’s relevant for genetics.
And Lastly, describe this sensation of dizziness more.
Your pain sounds much less cardiac and concerning in consideration of this new info; which is good.
I would still throw a holter on at least and see what comes up. But that’s just me. Im big on holters for pretty much everyone anyways. I’d probably also stress just to be safe.
I wouldn’t expect to see anything on the stress based on what you’re saying. However these are very Easy, safe and non-invasive tests. There’s not really much argument for NOT doing them apart from conserving resources.
Dizziness is always an interesting symptom here, perhaps Moreso than pain. You say all of this only happened once though which is reassuring but certainly if you have a problem with that dizziness coming back more than once or twice it would be of real interest to figure out what’s going on there.
Could it be anxiety? I mean sure, of course it can! That’s sort of a diagnosis of exclusion though in my opinion.
I would request a second opinion or get a referral for cardiology to screen for ectopy and ischemia just for the sake of being thorough; if within your means.
