I'm sorry to hear that you're both dealing with the same issues. I wonder if the RSD could be the culprit in my case as well. It's scary because the symptoms does mimic a heart attack. As you know, the sympathetic nerves can signal pain in any area of our body. I'm going to see a Neurologist just to follow up but I'll also share the information that you provided as well.

Thanks so much for sharing with me!
