God doesn't write prescriptions. Panic Attack. I know it does not sound like what it should be called but I get the same things. Screaming chest pain that lasts for short bursts but literally drop you to your knees. It hurts to breathe it feels like a white hot knife is in your heart, through the sternum. Google "Panic attack" and see if these are what you are getting if they are then tell your doc. if you aren't having them research what they are and tell your doc. they dont know everything, some are quite stupid or lazy. Best wishes.

if you go to the er, tell them just that. that your pain is 10+ out of 10, like before. tell them you want to get additional testing.

Talk to your neurologist, or whoever is prescribing your meds, and tell him/her about all of these conditions you are experiencing. They may need to change some of your meds of the strength of the meds.

I’ve had the chest pain before, I found out that it was my meds, it’s better now if not still a little painful but it’s worth considering them to be the problem

Just tell the doctors at the er about your pain and that you need the additional testing like Bryan said. But most importantly, put it in God's hands and leave it there.
