I also found this:
Q. I sometimes get excruciating chest pain out of the blue "" almost never when I am exercising or doing something physical "" that gradually goes away by itself. My doctor calls it vasospastic angina. Can you give me more information?
A. Your chest pain comes from sudden constrictions of a coronary artery. These spasms narrow the artery and temporarily stop blood flow to part of the heart. The pain you feel is the heart's response to lack of oxygen and nutrients and the buildup of waste products. It's akin to a muscle cramp in your leg, and is the same sensation felt by people with classic angina.
I'm gonna throw this in just cause I think it's very important:
If panic attacks have been a recurring problem, write the four basic steps on a little card, with a list of sample Coping Statements on the back. Mark the card with bright stripes to make it easy to find in your wallet, and keep it with you everywhere you go until you memorize the steps and know them thoroughly. Study these steps and learn them in advance. If you have a panic attack, get out your card immediately and follow it exactly. Once you learn these steps you won't need the card.
Full Resolution
If you experience panic attacks more often than occasionally I strongly suggest that you work with a practitioner to resolve the cause of your anxiety. You owe it to yourself to be free of anxiety. Permanently resolving issues of anxiety is one of my areas of specialty.
The Four Steps:
1) Relax.
2) Stop Negative Thinking.
3) Use Coping Statements.
4) Accept Your Feelings.

Sometimes my heart "flutters" and the cardiologist actually used that word to describe it but didn't experience it with the Raynaud's symptoms you're also describing. Hope you're better soon. Don't ignore chest pain, ok?

Hello Free, yes, I get the fingers numb, but not sure about your
upper chest, Urgent Care/PC Dr or ER if its really bad.
Here is our hands & feet deal:
Raynaud’s phenomenon is a condition that affects blood flow to the arms and legs, also called the extremities. It occurs when the blood vessels that feed the fingers and toes get smaller in reaction to cold or emotional stress (this event is called a vasospastic attack).
Sending hugs you feel better soon. Don't touch anything hot. When I do, veins in my hands start hurting so badly, then they burst, turning purple & goes away after a couple of hours. It's very scary, I have been dealing with this the last two days. It is no fun at all.
