I know exactly what you are feeling like right now. I don't want this to scare you, but just to share my experience. Seven years ago I was diagnosed with Raynaud's ... just cold & I mean super, duper freezing cold all of the time! about
a year later, I too started experiencing chest pain & numbness in my face (but no swelling). This went on for a couple of days - the docs couldn't figure it out. I ended up in the ER one night feeling like I was having a heart attached at age 23! Ended up fluid had developed around my heart --- that had to be removed (peracardio effusion). After that episode, my Rheumy determined I'd progressed into Lupus.
Remember, I am by no means trying to scare you - I just remember feeling terrible & no one having any suggestions or solutions.
I hope this helps! (If the chest pains persist, ask for a chest x-ray and echocardiogram of your chest cavity).
I have Lupus ... Lupus doesn't have me.
