Hi my husband became very ill 3 years ago, He is on a liver transplant list,, So I am his caregiver 24/7,, One year after he got sick, I would Be going to the store and all of a sudden I became really freaked out,, I would sweat, dizzy, it was awfull I went to the emerg 3 times in a month, I guess they thought I was nuts or something cause they could' tell me what was wrong. So I went to my GP he told me it was a panic attack and stress, He wanted to give me pills I said no I will deal with it. And 8 months ago I told my GP ok give me pills, Then I stopped smoking, Then a month ago I started sweating felt dizzy even when I was sitting, my heart rate went way up, I have high blood pressure put im on meds, So anyway my doctor told me to stop taking the night pill for stress because it can cause a racing heart, So I threw away the pills bought a pack of smokes and Im done with pills,, The best way to help yourself is, You know when you get those feeling just go lay down till they stop, I just said to my self it's time to take control and I did,As for sleeping I was up 42 hours straight last week,, I have a hard time sleeping but again I sleep when I sleep.. Take care of you self If your strong enough just get rid of the stress in your life and think positive good luck
Wrist pain doesn't have anything to do with a heart attack as far as I know, so to start you need to avoid complicating the issue.
Since you have lurked, you know that lots of people have had your symptoms, but got a clean bill of health from ER afterwards. The only time I got some bad "symptoms" I kept hoping they would go away for days, but finally went to ER where they said all was ok.
The doc told me I would have been dead if anything was wrong that long, so if you end up going again you might want to talk to doc about that in case whatever they say about prolonged pains helps put your mind at rest if you have future "symptoms". Here is an article about a guy who can't stop going to ER over heart worries.

I bet most people however accept that there is no problem and the anx disappears after one or 2 diagnosis come up negative, so try to work on accepting the reality and for sure stay away from google, because you can always find someone somewhere in history who had a heart issue and your symptoms, so you will just end up feeling bad for no reason afterwards.
